Why Are My Teeth Sensitive After Whitening?

why-are-my-teeth-sensitive-after-whitening

It is perfectly normal for teeth to feel sensitive after whitening – after all, your teeth are undergoing a transformative procedure. However, there are multiple factors that may be amplifying your discomfort. By identifying these factors, you can manage your pain for a smooth, fuss-free teeth whitening experience. Skip to:

Why are my teeth sensitive after whitening?

As mentioned earlier, there are many reasons as to why you have sensitive teeth. Whitening gels, an incorrect application technique, diet – these are just some of the contributing factors.

The bleaching agents are at work

Allow us to use carbamide peroxide, the key whitening agent found in our kit, as an example. Once carbamide peroxide comes into contact with the surface of the tooth, it releases hydrogen peroxide. This then acts as a bleaching agent, lifting stains from the tooth and whitening the enamel. These chemicals make the tooth more porous. As a result, the nerves inside the teeth are vulnerable to sensitivity-inducing stimuli such as very hot or cold food and drink.

You are not using the treatment correctly

If you are using an at-home kit and have after-teeth whitening sensitivity, there is a chance that it is user error. Wearing the gel for longer than the recommended time will likely lead to discomfort. Additionally, if you are using trays and filling them with too much gel, there is a chance that the substance can spill onto the gums and cause a burning sensation.

Your diet is at fault

Very hot or very cold foods and drinks often create sharp stinging sensations. If possible, try to avoid consuming anything at an extreme temperature and wait for it to be lukewarm, especially in the first 48 hours when your teeth are at their most sensitive. Spicy, acidic and sugary foods may also trigger discomfort. Finally, it is important to remain hydrated – if you are not drinking enough water, your tooth sensitivity can feel amplified.

There are underlying oral health problems present

We recommend undergoing a comprehensive oral health check prior to your treatment. This is to identify any existing problems that have the ability to cause (or aggravate) teeth whitening sensitivity. Problems include gum disease, tooth decay, cracks, cavities and loose fillings. At YDS, you will be required to attend a £95 consultation to check you are eligible for teeth whitening treatment.

You are using a DIY tooth whitening kit

These types of kits come with extra risks as they lack proper testing. Some sets use abrasive gels and pastes which may damage your enamel and lead to pain. Others use generic whitening trays that are easily overfilled. Do your research and choose a highly rated, dentist-led kit that you can trust. Or, go to a private dental clinic and have the treatment carried out by a qualified professional.

How long after teeth whitening does sensitivity last?

The first 48 hours are when you are most likely to have sensitive teeth. After this period, tooth whitening pain should subside. However, if it has been a few weeks since your treatment has ended,  and you are still suffering, we recommend booking an appointment with your dentist.

Managing tooth sensitivity after whitening

To help manage your discomfort, we have compiled our top 10 ways to minimise tooth sensitivity caused by whitening.

  1. Clean your teeth with a soft-bristled toothbrush and sensitive toothpaste
  2. Avoid very hot or very cold food and drink
  3. Take your usual over-the-counter pain medication
  4. Strictly follow the instructions of your teeth whitening treatment
  5. Rinse with saltwater to help alleviate discomfort and minimise swelling
  6. Apply desensitising gels – ask your dentist for recommendations
  7. Drink with a straw
  8. Limit the amount of time you are wearing the teeth whitening product
  9. Wait longer in-between treatments
  10. Address any pre-existing oral health concerns

Why choose Yorkshire Dental Suite teeth whitening?

Patients looking for an at-home tooth whitening kit that is safe and effective should choose Yorkshire Dental Suite. We use a prescription 16% concentration of carbamide peroxide to provide a dazzling smile that lasts up to 12 months. Over-the-counter kits in comparison do not contain a high enough percentage of the whitening agents, so they generally tend to be less effective, especially on teeth that are yellow or discoloured. Plus, we use SuperFit™ trays to ensure 360° whitening that isn’t patchy or streaky. Finally, our treatment is prescribed by dentists registered with the GDC (General Dental Council), so you can be sure that your teeth won’t suffer. Conclusion: Please be assured that teeth sensitivity after whitening is common, and typically subsides within a few days. If you have any concerns about the treatment ahead of starting, or need advice on managing pain, do not hesitate to contact us. We will help you in any way possible.
