A Brief History Of Teeth Whitening

Teeth whitening date back to ancient Egypt. It was a sign of wealth, and the Egyptians used a paste made of wine vinegar and ground pumice stone. Then they applied this with a frayed stick, the original toothbrush.

The Egyptian method is not as bad as the Romans. The Romans used urine, and it worked because it contains ammonia. But thanks to new technology and advancement in science, we now have other safer and better solutions.

In the 17th century, before the existence of dentistry as a profession, barbers were the ones who took care of oral health. Their work involved pulling problematic teeth and also whitening teeth.

They did this by filing down the stained enamel and applying nitric acid on it. Please don’t try this at home. Then fortunately for man, in the 1960s, the dental profession was born.

Dentists identified that peroxide had teeth whitening properties, and 20 years later, the teeth whitening solutions began. Thick whitening gels containing carbamide peroxide were used to fill dental trays.

This technique is still widely practised today. This has bid us goodbye to sticks, urine, and metal files.

How To Get White Teeth

These days, there are many tried and tested methods of whitening teeth, and they are:

  • Coconut oil
  • Toothpaste
  • Lasers
  • Bleach
  • Trays
  • Strips
  • Gels

The best teeth whitening option that will suit you best depends on some factors like how fast you want to see results, how sensitive your teeth are, how much you have to spend, and how permanent you want the effect to be.

It is important to note that all the whitening techniques that will be covered here only work for natural teeth. Implants, veneers, fillings, and any denture will remain the same colour.

Causes Of Discoloured Or Stained Teeth

Well, before you bother about not having pearly white teeth in the first place, it is good you know that your teeth are not supposed to be brilliant white.

The enamel that coats your teeth is bluish-white, and its transparency can make the yellow colour of the dentine show. As we get older, our enamel gets thin.

This makes our teeth appear dark or become yellower overtime. In most cases, the yellowing process is hastened by the food we eat and what we drink.  Other external factors also play a role.

Factors That Affect Teeth Whitening Include:

  • Braces: These can help straighten crooked teeth, correct misalignment, and straighten your smile. However, they can affect the cleaning of your teeth and make them look less than white.
  • Smoking: Tobacco contains tar and nicotine that can stain your teeth. The stain can increase very quickly over the years if you continue to smoke or chew tobacco.

This is why the teeth of most heavy smokers are brown.

  • Sugary drinks: Sugar causes tooth decay, and this is a well-known fact. This is one of the reasons health experts warn about high intake of sugar and sugary drinks.

They destroy your enamel and make it wear away, and your teeth will also appear darker over time.

  • Wine: Red wine contains tannins. This turns your teeth into a shade of grey. White wine might not directly stain your teeth, but it darkens existing stains.
  • Tea: Black tea does more damages on your teeth than coffee. Even light herbal teas are not left out. They can erode the enamel and cause staining.
  • Coffee: The dark colour of coffee and its acidity have a damaging effect on your teeth.
  • Sauces: Sauces that are brightly coloured, such as tomato sauce and curries contribute to teeth staining. Even the acids present in tomatoes make this nightshade vegetable a double culprit.

If you are concerned about the colour of your teeth, you can opt for a creamy and lighter version to reduce the chances of tooth staining.

Berries: Berries are high in antioxidants, and they have a lot of amazing benefits. However, their deep hue can stain your teeth.

Some people think that the best way to whiten teeth is to avoid the things that stain them. This is not all that simple as we also need some of these nutrients in our bodies to live a healthy life. You can minimise the staining effects of certain foods by eating them alongside foods that prevent teeth stains.

Examples of such foods are cheese, cauliflower, celery, apples, lettuce, and carrots. They help clean the teeth through friction, and they also neutralise the acids produced from these foods that can damage the enamel.

No matter how hard you try to maintain white teeth, a time would come when you will be considering teeth whitening.

What Is The Cost Of Teeth Whitening?

Professional teeth whitening is more expensive than many home treatments. However, it is advised by our dentists London to go for professional teeth whitening.

You will meet with our dentist and pay for his/her expertise, and you will be advised of any risks, and the whitening treatment that would be suitable for you.

For more expensive treatments, many dentists offer a payment plan. You can spread the cost, and can also consider taking a dental loan.

Different Teeth Whitening Options

Home Teeth Whitening Kits

This is one of the most popular teeth whitening options because it is more convenient and affordable. There are many kinds of teeth whitening kits in the markets.

All of them contain a bleaching agent which sits in a tray (like a mouth guard) inside your mouth. The application time varies within 10 and 30 minutes daily, and a single treatment course lasts for 1 to 2 weeks.

This method makes teeth whitening easy. You can do this in the comfort of your home without much disruption to your daily activities and schedules.

Here are some things you have to consider when choosing home teeth whitening kit.

  • Place of manufacture: In some places like the UK, EU, and the US, they are stricter regulations that govern the ingredients used in teeth whitening gels. This is not the same case as other countries.

It is always advisable to check the list of ingredients; this will help you know what you are putting in your mouth. You also have to know the country the product was manufactured from so you can understand the regulations it adheres to.

  • LED whitening kits: This is also known as “blue light whitening kits”. These products come with a LED light that hastens the process of bleaching.

Some bleaching kits come without a LED light. In this case, they come with an accelerator fluid. You apply this over your teeth before the gel.

  • Mouldable trays vs Fixed shape: Some kits have fixed shape mouth trays while others have thermoforming trays. Thermoforming trays must be put in boiling water first and then moulded to take the shape of your teeth.

This helps provide a better fit as this will ensure that the gel stays on your teeth. However, many people cannot master the moulding process.

They prefer to make use of the ready-to-use fixed shape trays.

At our dental clinic London, our qualified dentists usually recommend two home whitening kits. They are made in the US and France. Also, they are made of high-quality ingredients that conform to regulations.

Smile Avenue Professional Tooth Whitening Kit

This is a new high-quality kit that is new to the UK. It is produced by Smile Avenue, and it is made in the US. The gentle whitening gel formula is used to make this product.

You will get a cleaning spray which will be used to brush your teeth before the whitening process. Then the mouth tray will be attached to the LED accelerator light.

This is done 20 minutes every day, and the treatment course lasts for a week to 2 weeks. This kit contains 3 X 10ml syringes of gel, and this is more than what you get with other kits.

You should see a noticeable result after 1 to 2 weeks of use. There is a shade guard provided. You can check your result against that.

Very Good Smile Professional Whitening Kit

This high-quality kit is made in France. It conforms to the EU regulations for cosmetic procedures, and it is easy to use. It comes with a LED light which you will attach directly to the fixed shape mouth tray.

It is recommended you use it for 20 minutes a day and it has gels that can last for ten applications. If you have sensitive teeth, this is a good option. Its formula is more gentle than other brands in the market.

This kit also comes with a 30 days money-back guarantee. If you are unhappy with the results or you developed problems while using it, you get your money back in full.

You can buy separate gel refills if you have finished your treatment. This will prevent you from buying a whole new kit every time you want to whiten your teeth.

Teeth Whitening at the Dentist

If you have enough money and time, it is a good idea to visit our dentist London and discuss teeth whitening. Their treatments are more effective than these home whitening kits, and they know how to go about this safely.

They can even help you if you have any side effects. There are three main types of whitening treatment in a dentist’s office. They are:

  • Professional bleaching

This is a cheaper form of teeth whitening offered by dentists. Custom trays are used to apply the professional tooth whitening gel. This gel is stronger than those in the home kits, so it produces better results.

First, your dentist will take impressions of your teeth. This will be used to create custom mouth trays. When they are ready, you can complete your teeth whitening treatment at home.

You can even wear some professional teeth whitening gels overnight. This is helpful if you don’t have time to wear your trays during the day.

However, you have to ask our dentist London about the options they have to offer.

  • Enlighten teeth whitening

The enlighten  B1 teeth whitening system is a premium brand used in teeth whitening in the UK. It is used for severe cases of teeth stains.

People who want to achieve a guaranteed result of B1 brightness can also use this. This teeth whitening process involves the use of a kit which contains everything you need.

This system produces long-lasting results, thereby giving you a brilliant and winning smile. You can walk into our dental clinic.

  • Zoom teeth whitening

Zoom whitening uses technology from Philips, and it works in a way similar to that of laser whitening. The only difference is that it uses LED light to hasten a whitening agent.

This method is less intense, and it also has a low chance of sensitivity. However, it has a longer treatment time which usually consists of 3 to 4 sessions of 45 to 60 minutes.

This method of teeth whitening can be followed with home teeth whitening treatment to elongate the results.

  • Laser teeth whitening

Laser bleaching makes use of laser light to hasten the bleaching effect of a concentrated gel that is applied on the teeth. This is the most expensive method of teeth whitening, and it is also the closest you can get to instant teeth whitening.

Before beginning this process, your dentist will apply a rubber seal. This will protect your gums, and then your teeth will be covered with a bleaching product.

The product might contain hydrogen peroxide. Laser light will be shone on your teeth, and the whitening will occur. This is faster than other treatments.

This treatment is intense, and it should give a clear result after one visit to your dentist. However, it has high risks of sensitivity after treatment.

Other Home Whitening Options

Even though teeth whitening kits are the most effective ways to whiten your teeth, there are still other options you can try at home.

You can use these methods to achieve gentle results, or you can use them to maintain the results gotten from other whitening methods.

  • Teeth whitening strips

These are placed directly on your teeth, and they are much cleaner and easier to use than trays and gels. Many brands claim theirs are peroxide-free, but some still depend on peroxide to whiten teeth.

These strips are placed on the teeth and left for around 30 minutes before they are removed. Some strips can naturally dissolve after 10 to 15 minutes of wear. You can choose to go for this.

Whitening strips are highly effective in brightening the front teeth. However, they are not effective for the back teeth and people with uneven bite surfaces.

Teeth-whitening strips are difficult to reach other parts of the tooth, thereby giving a result that is not uniformed. However, they are cheap and can produce fast results.

You can see your desired results within one week.

  • Teeth whitening pens

These devices are more like brushes; they are made of a small tube of gel. A built-in brush applies this gel directly to the teeth. These pens usually contain hydrogen peroxide, and some brands free of hydrogen peroxide are also available.

They are convenient and can be carried everywhere you go. You can also use them whenever you have the time. The treatment usually lasts for 1 to 2 weeks, and it requires two to four applications daily depending on the brand and manufacturer.

This method will get you a few shades whiter, but you won’t get bright white teeth.

  • Whitening toothpaste and toothbrushes

There are many brands of whitening toothpaste in the market, including its whitening versions.

These whitening toothpaste can hurt. They contain abrasives which can scratch your enamel. When they are used daily in brushing the teeth, they tend to cause sensitivity after some time.

These whitening toothpaste only removes surface stains. They do not alter the colour of the teeth themselves. Whitening toothpaste will not work for someone with naturally yellow teeth.

However, this method can prolong the whitening gained from other methods of teeth whitening. This is the cheapest teeth whitening option. It is a popular option used in giving your smile a boost.

Certain toothbrushes are also designed to remove stains from the teeth. And they are available in both the manual and electric form.

Natural Ways to Whiten Teeth

If you are willing to trade quick results for a natural approach, then you can try the natural teeth whitening procedures below.

However, you must know that this natural approach won’t give you a dazzling white smile overnight. But they can make your teeth white over a longer time, and they are highly effective in keeping your teeth clean.

  • Coconut oil pulling

This is the act of swishing coconut oil around your mouth for 10 to 15 minutes. This is an Ayurveda technique for improving oral hygiene and preventing dental problems.

You have to rinse and brush your teeth immediately after this, and as you continue, you will notice that your teeth feel cleaner.

  • Homemade whitening paste

You can make effective teeth whitening paste at home by mixing baking soda and a tiny amount of hydrogen peroxide. Mix it until you get a runny consistency.

Brush your teeth and apply this paste on them. Let it sit on your teeth for 30 seconds, and then you rinse them off.

  • Apple cider vinegar

This is a highly effective home remedy for removing teeth stains. Rub this liquid on your teeth using clean cotton wool or your fingertips.

Leave it to stay for at about one minute and rinse off with water and then you brush normally. To get a good result, continue doing this for at least one month.

  • Mashed strawberries

Apply this paste directly to your teeth and leave it for some minutes before washing it off. Make sure you rinse your mouth thoroughly afterwards.

  • Activated charcoal

This is also a highly effective remedy for teeth whitening. But it will darken your whole mouth; however, there is nothing to fear here. Once you wash your mouth, you will discover that your teeth are sparkling and bright.

You can get activated charcoal as a powder or as toothpaste. It seems counter-intuitive to apply something black on your teeth to make them white.

It works, and that is a good reason why charcoal toothpaste and powders are popular now.

  • Very good smile teeth whitening powder

This is a popular product in the UK used in whitening teeth at home. It is all made from natural ingredients, and its 30g tube contains enough powder that can last you for 2 to 3 months for daily use.

You can make homemade toothpaste by mixing it with other ingredients, or you mix it with water and apply it directly to your teeth. It is a non-abrasive formula.

You can use it to expel teeth stains gotten from wine, coffee, tea, and tobacco.

Whitening Sensitive Teeth

Some people experience unbearable pain and sensitivity after whitening their teeth. If you have experienced sensitivity in the past or have a sensitive tooth, it is good you let our dentist London know.

Your dentist will apply topical pain relief to help you manage the pain you will experience after whitening. If you are using home whitening treatment, you should follow the manufacturer’s instructions strictly.

Then also try building up the recommended time. For instance, if the instruction says you should apply the gel for 15 minutes, you first start with five minutes.

This will help you see how your teeth feel, and you will know if it makes your teeth sensitive or not. Products that do not contain hydrogen peroxide create less sensitivity.

Fluoride and potassium nitrate are effective pain relievers you can use. You can contact our dentists at Harly street London if you need professional advice before whitening your teeth.

How to Keep Your Teeth White After Treatment

The truth is that there are no true permanent teeth whitening solutions. This means your teeth can get stained again after whitening.

However, there are measures you can put in place to help the whitening effect last longer. It can last as long as you want if you do these things.

Below are some tips to imbibe:

  • Reduce your intake of foods and drinks that can stain your teeth
  • You can take in sugary drinks, acidic drinks, and herbal teas through a straw.
  • Rinse your mouth with water after eating teeth-staining foods and drinks. You can also chew sugar-free gum.

Lastly, you have to maintain good oral hygiene. Good dental health practices such as daily brushing and flossing will help maintain white teeth.

You should also try and visit a dentist at least once a year for a checkup. This will help our dentists London spot problems early and begin treatment immediately and also offer you professional advice.

All these will help keep your mouth clean and free from plaque and bacteria. These contribute to teeth stains and tooth decay.

Is it Safe to Whiten my Teeth?

Yes, teeth whitening is safe, and the most reliable way to go about this is to let an approved dentist do it for you. These dental professionals have been well-trained to carry out dental procedures.

They can identify the cases where whitening is not needed and advise you on that. For instance, people who have dental crowns and gum disease cannot whiten their teeth.

Local beauty salons or mobile whitening service will advertise teeth whitening, but you should know that they are not trained professionals.

In the UK, it is against the law for teeth whitening to be carried out by anyone who isn’t a qualified dentist. It is safe to use home whitening kit if you follow the instructions.

Don’t be tempted to exceed the recommended amount of gel. Don’t exceed the usage time; it is even better you reduce it but don’t go above it. Exceeding any of this can damage your teeth and your gum.

You can contact us if you are concerned about the risks of whitening your teeth. You can also talk to people who have done it before and ask about their experience.

Checking Teeth Whitening Reviews

No matter the teeth whitening method you choose to use, you can go online and find reviews. This will help you have an idea of what it is like and what to expect.

You can also check reviews about specific products like activated charcoal and home whitening kits. However, you must know that some brands give their products to social influencers for free in return for a video or review.

This should be disclosed in the review, and it will make it less impartial. Also, note that different people will have different experiences.

Their experiences in the result gotten, ease of use and sensitivity will differ. However, you should still check for reviews from others. This will help you decide on the type of teeth whitening treatment to go for.
