Tartar Buildup and Tooth Sensitivity: Causes, Symptoms, and Care

Tartar buildup and tooth sensitivity: Last Updated: September 22, 2026 | 7 min read

Tartar buildup and tooth sensitivity can occur together when hardened plaque irritates the gums and contributes to gum recession. As gum tissue recedes, more of the tooth root may become exposed.

Unlike the crown, the root has less protective enamel. Exposed root surfaces can therefore react more strongly to hot, cold, sweet, or acidic foods and drinks.

Tartar, also called calculus, forms when plaque hardens on the teeth. Once tartar develops, regular brushing cannot remove it completely. Professional dental cleaning is required to remove hardened deposits.

Why Tartar Buildup Can Increase Tooth Sensitivity

Tartar can create rough areas where plaque and bacteria collect. This buildup may irritate the gums and contribute to inflammation.

1. Gum Inflammation

Plaque and tartar can irritate gum tissue. Common signs include redness, swelling, tenderness, and bleeding during brushing.

When gum inflammation continues, the gums may pull away from the teeth. This can expose more of the tooth root and increase sensitivity.

2. Exposed Tooth Roots

Tooth roots have less protection than the visible crown. When the gums recede, exposed root surfaces can become more sensitive to temperature and touch.

This is one reason people with gum recession may notice discomfort while drinking something cold or brushing near the gum line.

3. Plaque and Bacterial Buildup

Tartar provides a rough surface that makes plaque control more difficult. Regular brushing and cleaning between teeth help control plaque before it hardens.

The American Dental Association recommends daily cleaning between teeth because these areas are difficult to reach with a toothbrush alone.

Common Symptoms of Tartar Buildup and Tooth Sensitivity

Tartar and gum problems may appear with several noticeable symptoms. These can include:

• Sharp discomfort when drinking hot or cold beverages
• Sensitivity to sweet or acidic foods
• Discomfort while brushing near the gum line
• Visible yellow or brown deposits on teeth
• Red, swollen, or bleeding gums
• Teeth that appear longer because of gum recession
• Persistent sensitivity around certain teeth

Tooth sensitivity can have several causes. Gum recession, exposed dentin, tooth wear, and other dental problems may also contribute to sensitivity. Persistent symptoms should therefore be checked by a dental professional.

Tartar Buildup and Related Oral Health Problems

Tartar can occur in different areas of the mouth. Its location may affect the symptoms people notice and the type of dental care they need.

For example, tartar may develop after orthodontic treatment, beneath the gum line, behind the lower front teeth, or alongside persistent bad breath. These related topics can help readers understand different tartar concerns.

Tartar After Braces Removal

Braces create additional areas where plaque can collect. After orthodontic treatment, some people may notice deposits that were difficult to clean around brackets and wires.

Learn more about tartar buildup after braces removal and the oral care steps that can help protect teeth after braces.

Tartar Under the Gums

Tartar can also develop around or below the gum line. Deposits in these areas may be difficult to reach with ordinary brushing and can contribute to gum inflammation.

Read tartar buildup under the gums to understand why deposits in this area deserve professional attention.

Tartar and Bad Breath

Persistent bad breath can have several causes. Plaque, gum disease, dry mouth, food debris, and other oral conditions can contribute to unpleasant breath.

If you are dealing with persistent odor, read about tartar buildup and bad breath and the factors that may contribute to it.

Tartar Behind the Front Teeth

The area behind the lower front teeth can collect plaque and tartar. Saliva flow in this area may also contribute to mineral buildup.

Learn why tartar buildup behind the front teeth is common and how daily cleaning can help control plaque.

Tartar Buildup in Children

Children can also develop plaque and tartar when daily brushing and cleaning between teeth are inconsistent. Early oral care helps children build healthy habits.

Parents can learn more about tartar buildup in children and simple prevention steps for younger teeth.

How Tartar and Tooth Sensitivity Are Managed

The right approach depends on the cause and severity of the problem. A dental examination can help identify whether tartar, gum recession, tooth decay, or another condition is causing sensitivity.

Professional Dental Cleaning

A dentist or dental hygienist can remove hardened tartar using professional cleaning methods. If gum disease has progressed, deeper cleaning such as scaling and root planing may be recommended.

Desensitizing Toothpaste

Some toothpaste products contain ingredients designed to reduce tooth sensitivity. The ADA notes that certain desensitizing ingredients can help reduce sensitivity when used as directed.

Gentle Brushing

Use a soft-bristled toothbrush and gentle movements along the gum line. Aggressive brushing can irritate the gums and may contribute to gum recession.

Cleaning Between Teeth

Floss and other inter-dental cleaners can help remove plaque from areas that toothbrush bristles cannot reach effectively. Daily inter-dental cleaning supports healthy gums and helps reduce plaque buildup.

Prevention Tips for Tartar and Tooth Sensitivity

A consistent routine can help control plaque and support healthier gums.

• Brush twice a day with fluoride toothpaste.
• Clean between teeth every day.
• Use a soft-bristled toothbrush.
• Brush gently around the gum line.
• Limit frequent exposure to acidic foods and drinks.
• Schedule dental examinations and professional cleanings as recommended.

These habits help control plaque before it hardens into tartar. Professional cleaning remains important because hardened tartar cannot be removed completely through brushing alone.

When Should You See a Dental Professional?

Schedule a dental evaluation if sensitivity continues, becomes stronger, or occurs together with gum swelling or bleeding.

Professional assessment is especially important when you can see tartar along or below the gum line. A dentist can determine whether you need routine cleaning, periodontal treatment, or another form of dental care.

FAQ

Does removing tartar reduce tooth sensitivity?

It can help when tartar and gum inflammation are contributing to the problem. However, sensitivity can have other causes, so persistent symptoms should be evaluated.

Are sensitive teeth permanent?

Not always. The outcome depends on the underlying cause. Treatment may improve sensitivity when the cause is identified and managed.

Should I avoid cold drinks?

Reducing very cold or acidic foods and drinks may help limit discomfort. However, persistent sensitivity should be evaluated rather than managed only by avoiding triggers.

Can brushing remove tartar?

Brushing helps remove plaque before it hardens. Once plaque becomes tartar, professional dental cleaning is needed for removal.

Can Dental Pro 7 remove tartar?

Dental Pro 7 should not be presented as a substitute for professional tartar removal. Hardened tartar requires professional cleaning. Dental Pro 7 may instead be considered as part of a broader daily oral care routine.
