Is it normal for teeth to be sensitive after whitening

Teeth whitening is a popular cosmetic procedure that helps to enhance the appearance of teeth by lightening their color. It is common for people to experience some level of tooth sensitivity after undergoing a whitening treatment. In this article, we will explore the reasons behind tooth sensitivity after teeth whitening and provide advice on how to alleviate the discomfort.

1. Causes of tooth sensitivity after whitening

1.1 Bleaching agents in whitening products

Most teeth whitening products contain bleaching agents such as hydrogen peroxide or carbamide peroxide. These chemicals work by penetrating the enamel and breaking down the stains, resulting in a whiter appearance. However, they can also temporarily weaken the enamel and irritate the nerves inside the teeth, leading to sensitivity.

1.2 Gum irritation

During the whitening process, some of the whitening gel may come into contact with the gums. This can cause irritation and inflammation, making the teeth more sensitive to various stimuli.

1.3 Pre-existing dental conditions

Individuals with pre-existing dental conditions such as gum recession, enamel erosion, or cavities may experience heightened sensitivity after teeth whitening. This is due to the exposure of sensitive areas of the teeth to the bleaching agents.

1.4 Incorrect usage of whitening products

If teeth whitening products are used improperly, such as leaving them on for longer than instructed or using a higher concentration of the bleaching agent, it can result in increased tooth sensitivity.

2. How long does tooth sensitivity last after whitening?

The duration of tooth sensitivity after whitening can vary from person to person. In most cases, the sensitivity is temporary and should subside within a few days to a couple of weeks after the treatment. However, in some individuals, it may persist for a longer period.

3. Alleviating tooth sensitivity after whitening

3.1 Use desensitizing toothpaste

Desensitizing toothpaste contains ingredients that can help to relieve tooth sensitivity. It is recommended to use this type of toothpaste before and after teeth whitening to minimize discomfort.

3.2 Avoid hot and cold substances

During the period of tooth sensitivity, it is advisable to avoid consuming foods and beverages that are extremely hot or cold. These can trigger sensitivity and cause discomfort.

3.3 Apply a fluoride gel or varnish

Fluoride gel or varnish can be applied to the teeth to strengthen the enamel and reduce sensitivity. It is best to consult a dentist for professional advice on the use of fluoride products.

3.4 Limit consumption of acidic foods and drinks

Acidic foods and drinks, such as citrus fruits and carbonated beverages, can exacerbate tooth sensitivity. It is recommended to limit their consumption during this period.

4. Professional teeth whitening procedures

Professional teeth whitening procedures, performed by dentists, are generally considered to be more effective and less likely to cause sensitivity compared to over-the-counter products. The average cost of professional teeth whitening ranges from $500 to $1,000, depending on the location and the specific treatment chosen.
