Is it Normal for Teeth to Feel Sensitive After Dental Cleaning?

When it comes to dental hygiene, regular dental cleanings are an essential part of maintaining healthy teeth and gums. However, some individuals may experience tooth sensitivity after a dental cleaning. This article aims to shed light on the common question, “Is it normal for teeth to feel sensitive after dental cleaning?” We will explore the causes of tooth sensitivity, ways to manage it, and provide expert answers to frequently asked questions.

After a dental cleaning, it is not uncommon for teeth to feel sensitive. This sensitivity is usually temporary and should subside within a few days. The process of dental cleaning involves the removal of plaque and tartar buildup, which can expose the underlying dentin. Dentin contains microscopic tubules that connect to the nerves of the teeth, making them sensitive to various stimuli.

Sensitive teeth after dental cleaning can manifest as discomfort or pain when consuming hot or cold foods and beverages, breathing in cold air, or brushing your teeth. The severity of sensitivity varies from person to person, and while it can be bothersome, it is generally considered normal.

Factors Contributing to Tooth Sensitivity after Dental Cleaning

Gum Recession: 

If you have receding gums, the roots of your teeth may become exposed. These roots do not have the protective enamel layer and are more sensitive to external stimuli, leading to increased sensitivity after a dental cleaning.

Enamel Wear: 

Tooth enamel protects the underlying dentin. However, if your enamel is thin or worn, the dentin becomes exposed, resulting in tooth sensitivity.

Aggressive Dental Cleaning: 

The technique and pressure used during a dental cleaning can influence post-cleaning sensitivity. Aggressive scaling or using a high-powered polishing tool can cause temporary sensitivity.

Teeth Grinding or Clenching: 

Bruxism, the habit of grinding or clenching your teeth, can lead to enamel wear and dentin exposure, making your teeth more sensitive after a dental cleaning.

Tooth Decay or Cavities: 

If you have tooth decay or cavities, your teeth may already be sensitive. Dental cleaning may exacerbate this sensitivity temporarily.

Recent Dental Procedures: 

If you have undergone dental procedures such as fillings or root canals before the cleaning, your teeth may be more sensitive.

Normal Sensitivity vs. Prolonged Sensitivity After Dental Cleaning

Dental cleaning, whether it’s a routine cleaning (prophylaxis) or a deeper cleaning like scaling and root planing, can sometimes result in sensitivity. Here’s a breakdown of what to expect and when to be concerned:

1. Typical Duration of Post-Cleaning Sensitivity:

Normal Sensitivity:

Duration: Usually lasts for a few hours to a few days after the procedure.

Characteristics: Sensitivity to cold, hot, or sweet stimuli can be common. It often feels like a short, sharp sensation.

Reason: Removal of plaque and tartar, especially in deeper cleanings, can expose areas of the tooth that were previously covered, leading to transient sensitivity.

Prolonged Sensitivity:

Duration: If sensitivity persists for more than a week, it could be a sign of an underlying issue.

Characteristics: Continuous pain or throbbing, a sensitivity that doesn’t fade with time, and pain when biting down can all be indicative of deeper issues.

Reason: Potential causes could include tooth decay that wasn’t evident before the cleaning, exposed tooth roots, a crack or fracture in the tooth, or gum recession that exposes the root surfaces.

2. Signs That Sensitivity Might Be Due to a Deeper Issue:

Intensity and Duration: Pain that is intense, lasts longer than a week, or worsens over time.

Reactive Pain: Pain when biting down or chewing, which could indicate a cracked tooth or issues with the tooth’s inner pulp.

Swelling: Any noticeable swelling or abscess in the gums.

Spontaneous Pain: Pain that occurs without any triggers like hot, cold, or sweet stimuli.

Discoloration: A tooth becoming gray or dark, indicating potential nerve damage.

History of Trauma: A tooth that has previously suffered trauma may develop issues later on.

If you experience prolonged sensitivity or any of the signs indicating a deeper issue, it is essential to return to your dentist for a follow-up examination. They will be able to diagnose the cause of the sensitivity and recommend appropriate treatment.

Managing Tooth Sensitivity after Dental Cleaning

While tooth sensitivity after dental cleaning is usually temporary, there are several strategies you can implement to manage the discomfort:

1. Use Desensitizing Toothpaste

Desensitizing toothpaste contains ingredients that help block the transmission of sensations from the tooth surface to the nerves. Using desensitizing toothpaste regularly can provide relief from tooth sensitivity.

2. Practice Gentle Brushing

Brush your teeth using a soft-bristled toothbrush and gentle circular motions. Avoid using excessive force or brushing vigorously, as this can further aggravate sensitivity.

3. Use a Fluoride Mouthwash

Rinsing your mouth with a fluoride mouthwash can strengthen tooth enamel and reduce sensitivity. Incorporate this into your daily oral hygiene routine for optimal results.

4. Limit Acidic and Sugary Foods

Acidic and sugary foods can contribute to tooth sensitivity. Limit your consumption of these foods to minimize sensitivity and maintain good oral health.

5. Wear a Nightguard

If you grind or clench your teeth, wearing a nightguard can help protect your teeth from further damage and reduce sensitivity. Consult with your dentist to get a custom-fitted nightguard that suits your needs.

6. Seek Professional Advice

If tooth sensitivity persists or worsens after a dental cleaning, it is advisable to consult your dentist. They can assess the underlying cause and recommend appropriate treatments or interventions to alleviate your symptoms.


Experiencing tooth sensitivity after a dental cleaning is a common occurrence. It is usually temporary and can be managed with proper oral hygiene practices and professional guidance. By understanding the underlying causes of sensitivity and implementing appropriate strategies, you can alleviate discomfort and maintain optimal dental health. If tooth sensitivity persists or worsens, it is always advisable to seek professional advice from your dentist.
