How to Prevent and Treat Sensitive Teeth after Whitening?

04/04/23 12 MIN Read

For numerous reasons, teeth whitening has grown in popularity over the past few years. Some people might desire a whiter smile due to discolored teeth. Or perhaps all you want is to feel more confident.

Whitening products have served as the solution for many. Yet, if you’ve ever whitened your teeth, you could have experienced momentary dental sensitivity or even gingival irritation. This is both normal and expected. Thankfully, there are a few simple ways to handle the discomfort and sensitivity after and during teeth whitening.

What causes Teeth Sensitivity after Whitening?

As a result, you could have brief bouts of tooth discomfort or sensitivity following teeth whitening with:

  • Cool foods or beverages.
  • Food that is sweet, sour, or acidic.
  • Air.
  • Brushing your teeth.

Carbamide peroxide and hydrogen peroxide are to blame for the sensitivity of the teeth after whitening. These are the components included in tooth whitening solutions the most frequently. By igniting a chemical reaction with the chromogens on the teeth, they both function. The bacteria known as chromogens grow on our teeth and stain them.

A lighter tint of the tooth is produced when chromogens and the peroxides in whitening treatments interact. The pulp or nerve inside the tooth, however, can occasionally become inflamed as a result of exposure to these peroxides.

How long does Teeth Sensitivity last after Whitening

After having your teeth whitened by a professional, they may be sensitive for a few days, weeks, or even months. Your individual situation and the potential tooth sensitivity will determine how long it lasts.

While it is hard for our experts to predict how long your teeth might remain sensitive, they may be able to predict whether you will suffer tooth sensitivity following a whitening session based on the quality of your current teeth and your past sensitivity history.

Temporary tooth discomfort and sensitivity are the most frequent adverse effects from utilizing teeth whitening treatments. Nonetheless, there are certain suggestions you may take to lessen the possibility of discomfort following the treatment. By using the suggestions below, you can get sensitivity alleviation.

Take Pain Relievers

Prior to having your teeth whitened, using an over-the-counter pain reliever like ibuprofen might help lessen sensitivity and discomfort. After your treatment, you can keep using this medicine to control any remaining sensitivity.

Use a Desensitizing gel

Desensitizing gels can quickly relieve the discomfort associated with tooth whitening. You should do this prior to receiving therapy. Rinse with water after leaving the gel on your teeth for the suggested amount of time.

Use desensitizing Toothpaste

Using a desensitizing toothpaste is one of the easiest and most efficient ways to alleviate dental sensitivity after whitening.

As suggested by the name, these kinds of toothpaste contain components that are not only soothing for those who have sensitive teeth but also work to lessen the sensitivity of the teeth as a consequence.

Make sure to brush your teeth with a toothpaste designed specifically for teeth desensitization within the initial 48 hours following your teeth whitening procedure. You might even choose to use this toothpaste permanently if you were susceptible to sensitive teeth prior to having your teeth whitened.

How to Prevent Sensitive Teeth after Whitening

Ask your doctor to prescribe or suggest a prescription-strength toothpaste or gel that is specially made to lessen sensitivity after teeth whitening.

Use a straw to drink

Anyone looking for advice on how to stop their teeth from becoming sensitive after bleaching might want to think about spending money on a high-quality reusable drinking straw.

Consuming liquids, especially cold ones, can be extremely unpleasant for people who have sensitive teeth if the liquid makes contact with the teeth. With a drinking straw, you may enjoy a beverage without worrying that the liquid will contact your teeth and bring you pain or suffering.

Avoid both hot and cold liquids

Avoiding hot and cold beverages is another easy and extremely efficient method you may use if you’re curious to know how to get rid of tooth sensitivity after whitening.

The last thing you should do if your teeth are sensitive after being whitened is drink something ice cold or extremely hot since these high temperatures can severely exacerbate your teeth’s sensitivity and cause you a lot of pain and discomfort.

Drinking beverages at room temperature is preferable, and as before, use a straw to prevent the liquid from coming in contact with your now very sensitive teeth.

Gently brush your teeth

If you’re wondering how to stop experiencing tooth sensitivity after whitening, switching to a toothbrush with softer bristles and brushing more slowly and gently can really make a significant impact.


Teeth whitening can be a great way to improve the appearance of your smile, but it can also cause sensitivity. The majority of whitening products may cause moderate tooth sensitivity and gum inflammation. However once your whitening procedure is through, this usually goes away within a few days.

The idea is to whiten your teeth with the least amount of discomfort possible. And the first step in doing this is involving your dental care professional. If you’re thinking about getting your teeth whitened, our team of professional dentists at NYC Dental Smiles is the best choice for you.
