Does teeth whitening for sensitive teeth exist? And if so, what are your best options?

This article will discuss everything you need to know about whitening sensitive teeth including the following topics and questions:

• How to whiten sensitive teeth
• Best teeth whitening kit for sensitive teeth
• What are the best whitening strips for sensitive teeth?

If you want to whiten teeth and avoid sensitivity it's important to know which ingredients cause sensitivity and which prevent it. But first, let's start with the causes of sensitive teeth, and how whitening your teeth may trigger pain and discomfort.

Teeth whitening and sensitive teeth

If you're reading this article, it's likely that you suffer from tooth sensitivity, especially during or after whitening cosmetic procedures. Teeth sensitivity can be an ache during a whitening procedure, or sharp pain when you consume hot or cold food and drinks.

Some of the potential causes of sensitivity include the following:

• Cavities
• Cracked or chipped teeth
• Gum disease
• Damaged or thinning enamel

However, for those with generally healthy teeth, sensitive teeth when whitening can be from bleaching sensitivity and dentin sensitivity.

Sensitive teeth after whitening with bleach

If your teeth are usually sensitive to hot and cold foods and drinks because of thinning enamel, then you're more likely to experience heightened sensitivity after a bleaching treatment.

During dental bleaching procedures, peroxide, in the form of gels or solutions, comes into contact with the teeth. These peroxide solutions penetrate the tooth structure and break down and remove stains within your dentin. This can cause many patients to experience bleaching sensitivity.

In fact, the reasons why patients experience bleaching sensitivity are still unclear. However, it is believed that the deep penetration of oxidative free radicals generated from peroxide towards the teeth pulp could produce sensitivity. Additionally, the usage of some light sources contributes to increasing the temperature in pulp, causing more discomfort after the procedure. 

Fortunately, it's only temporary and should go away within a couple of days.

Dentin sensitivity after whitening

Dentin sensitivity is a permanent type of sensitivity, unlike the type you can get from bleaching which is temporary. It can happen when stimuli come into contact with areas of your tooth that have exposed dentin.

When your enamel is thin or dentin is exposed, the peroxide in the bleaching solution can penetrate your dentin, causing pain, sensitivity, or discomfort.

Can I get my teeth whitened if I have sensitive teeth?

Even if you experience sensitivity, don't worry, teeth whitening is still an option for you. Just make sure to look for solutions that are specifically targeted towards people with tooth sensitivity.

Thankfully, there are plenty of options available such as:

• White strips
• Professional teeth whitening
• Whitening kits
• Toothpaste

We'll go over all of these, but first, let's look at the main whitening ingredients.

Teeth whitening ingredients

There are myriad ingredients used for lightening tooth colour, some more effective than others.

The ingredients that are perhaps the most effective may cause the most sensitivity. But, some of these systems provide a solution by including ingredients that help prevent or decrease sensitivity.

Let's take a look at the ingredients that can cause sensitivity and the ingredients that can relieve it.

Teeth whitening ingredients that trigger teeth sensitivity

Peroxides are one of the most effective and commonly used teeth whitening ingredients. But, they are suspected to be the primary culprit when it comes to teeth whitening sensitivity. Usually, it's in the form of hydrogen peroxide, although carbamide peroxide is sometimes used as well.

Peroxide passes through the tooth and actually changes the colour. Hydrogen peroxide is a weak acid that has oxidizing properties, allowing it to take apart complex stain molecules. A side effect of using it to whiten teeth is that it releases free radicals while it works which can cause damage to your enamel and gum tissue.

Usually, the pain, sensitivity, or discomfort experienced during or after a whitening procedure is only temporary. However, in cases where the whitening agent isn't applied correctly or for too long, it can damage the enamel permanently.

Teeth whitening for sensitive teeth in the UK

Some ingredients used in whitening toothpaste and whitening systems are meant to prevent or decrease tooth sensitivity. Fluoride is one of the ingredients that dentists use to strengthen enamel and reduce pain. They apply it straight to your teeth for a short amount of time to treat your teeth.

Sensodyne, one of the most popular brands of toothpaste for sensitivity includes the ingredient potassium nitrate to soothe the nerves inside your teeth and stannous fluoride to strengthen enamel.

The best whitening toothpaste for sensitive teeth is one that not only whitens your teeth but also remineralises and desensitises them at the same time.

Hismile's PAP+ Whitening Powder has the ability to make any toothpaste into a whitening toothpaste. It uses their PAP+ formula which helps to desensitise and remineralise teeth enamel as it whitens.

There are also products and professional in-office teeth whitening services that are designed specifically for those who have teeth whitening sensitivity. These treatments usually come with some sort of desensitising gel or serum and are applied prior to a bleaching procedure. Desensitising substances based on phosphate such as (DCPA) and (TTCP) have reported successful results in preventing sensitivity.

Smile Avenue Teeth Whitening Kit

A great non-peroxide teeth whitening kit to use with sensitive teeth is Smile Avenue's Whitening Kit, which uses PAP as its main whitening ingredient. Their whitening formula also includes the ingredient hydroxyapatite that helps to remineralise your teeth enamel which goes a long way in reducing any existing tooth sensitivity that you may have.

The full list of ingredients for Smile Avenue's whitening gel includes the following:

Sorbitol, Aqua, Phthalimidoperoxycaproic Acid (PAP), Propylene Glycol, Glycerin, Potassium Nitrate, PEG-8, Hydroxyapatite, Cellulose Gum, Hydroxyethyl Cellulose, Xanthan Gum, Saccharin Sodium, Menthol, Methylparaben, Aloe Barbadensis Leaf Juice, Chamomilla Recutita (Matricaria) leaf Extract, Punica Granatum Seed Oil, Sodium Bicarbonate, Propylparaben

Smile Avenue's whitening formula comes in the form of whitening pens so that you can paint the whitening gel onto your teeth before using the mouthpiece and a blue LED light to whiten your teeth. Although PAP does not cause any damage to your gum tissue it is still better to be able to control where the whitening gel goes, and ensure you cover all of your teeth.

Like Hismile's whitening kit, your teeth should feel stronger after using this whitening formula due to the remineralising properties of the hydroxyapatite.
