Why Teeth Sensitive After Cleaning

Visiting the dentist for a routine cleaning is essential to maintaining optimal oral health. However, some individuals may experience sensitivity after cleaning. In this article, we will explore the causes of sensitive teeth after cleaning and discuss ways to alleviate the discomfort.

Understanding Tooth Sensitivity

Tooth sensitivity is a common issue that affects many individuals. It occurs when the tooth's protective layer, known as enamel, wears away, exposing the underlying dentin layer, which contains tiny tubules leading to the nerves and blood vessels. These tubules allow for stimulation of the nerves, leading to pain or discomfort.

Causes of Tooth Sensitivity After Cleaning

1. Tooth Decay: Tooth decay that has reached the inner layer of the tooth can cause sensitivity if not treated promptly. A dentist will typically detect decay during the cleaning process.

2. Gum Recession: When gums recede, the roots of the teeth become exposed. The root surface does not have the same hard protective layer as the enamel, and this exposure may lead to sensitivity.

3. Abrasive Cleaning: Overly aggressive cleaning by your dentist can cause sensitivity. The use of abrasive cleaning tools can contribute to wearing away the protective layer. Therefore, dentists use fine and gentle polishing paste to clean the teeth.

4. Tooth Trauma: Teeth can become damaged due to injury or excessive force, causing sensitivity. This trauma may occur when your dentist is cleaning your teeth.

5. Teeth Grinding: Bruxism, or teeth grinding, can result in tooth sensitivity caused by the wearing away of the protective layer. Your dentist can detect any signs of grinding during the cleaning process.

How to Alleviate Tooth Sensitivity?

If you experience tooth sensitivity after cleaning, there are several methods to alleviate the discomfort:

1. Desensitizing toothpaste: Such toothpaste contains potassium nitrate, which helps to block the tubules' exposure, thereby reducing sensitivity.

2. Fluoride treatment: Dentists sometimes apply fluoride varnish to the teeth after cleaning, which helps to strengthen the enamel and reduces sensitivity.

3. Mouthwash: Rinsing your mouth with mouthwash after cleaning can help to reduce sensitivity by numbing the mouth.

4. Changing Brushing Technique: Using a softer toothbrush and a gentle brushing technique, can help to reduce tooth sensitivity.

5. Follow-up Appointment: If you are experiencing sensitivity after your cleaning, don't hesitate to contact your dentist, as there may be underlying issues causing the sensitivity. They may recommend further treatment such as fillings or root canal treatment.


Tooth sensitivity after cleaning is a common issue that is caused by multiple factors. Understanding the most common causes of sensitivity will help avoid it from happening. If you experience sensitivity after cleaning, try one or more of the remedies discussed in this article. If the pain persists, consult your dentist for further treatment options. Remember to continue to practice good oral hygiene daily.
