When Troubled Teeth Tingle: What it Means When Your Teeth Begin to Tingle

Whenever you experience a toothache or tooth pain/teeth tingle, you can be almost certain that something is wrong. However, besides pain and sensitivity, a tingling sensation is also a symptom of a troubled tooth.

If one or more of your teeth have begun to tingle, it might be time for a dental check-up. Tingling usually means that a tooth has suffered trauma of some sort.

Your Teeth Are Alive

Teeth are much more than just lumps of inert enamel. Each tooth contains a bundle of nerves and blood vessels called the dental pulp. This pulp allows your teeth to experience sensation. For example, if you bite into an ice cream, you soon regret doing so because of the jolt of pain you receive via your front teeth.

The dental pulp also lets you know when a tooth is in distress. A tingling sensation is a message from your tooth that something is wrong. Your tooth could be suffering from one of the following conditions.

Trauma Due to Bruxism

When a person grinds their teeth whilst sleeping at night, they are suffering from bruxism, also known as nocturnal grinding. Nocturnal grinding causes considerable damage to teeth. When you grit your teeth, for example, during heavy lifting, you are able to control the pressure you exert. However, whilst asleep, you have no such control and as a result, your teeth suffer damage.

Grinding not only wears away enamel, cracks teeth and damages fillings and other repair work, but it also irritates the dental pulp. When the pulp becomes irritated, the affected tooth may begin to tingle. This could indicate that the pulp is dying. If the pulp dies, it will begin to rot inside the tooth, causing an infection and subsequent dental abscess.

Trauma Caused by Over-Brushing

Enamel may be the hardest substance in the human body but that doesn’t mean a toothbrush cannot damage it. If you brush your teeth too vigorously each morning and night, you’ll wear away the enamel. Since your enamel protects the dental pulp, the less enamel there is, the more at risk the dental pulp is of becoming irritated.

Dentin, the spongy layer underneath enamel, contains thousands of tubules. This means that once the enamel layer has been worn away, temperatures, acids from food, and bacteria may irritate the nerve. Again, as a result, you may experience a tingling sensation in the affected tooth.

Faulty Fillings Cause Tingling

If a dental filling is faulty or in need of replacement, you may experience tingling. If the filling in question is new, that could mean that the filling is too high. In this case, your dentist can lower it so that it doesn’t interfere with your bite.

No matter what you suspect is causing your tooth, or teeth, to tingle, you should book a dental appointment just to be sure. If the dental pulp has become inflamed (pulpitis), then a dentist needs to perform a root canal on the tooth before the infection worsens.

Don’t take any chances with your teeth. If the dental pulp dies inside a tooth, it will rot, causing an infection and dental abscess, which can be painful as well as dangerous. Listen to your teeth and act quickly if you suspect the dental pulp is in distress.

Frequently Asked Questions About Teeth Tingling

Why do my teeth tingle?

Teeth tingle when the nerves inside the tooth become irritated. Common causes include enamel wear, teeth grinding (bruxism), tooth sensitivity, gum recession, cavities, cracked teeth, or faulty dental fillings.

Is tingling in teeth a sign of a cavity?

Yes, a tingling sensation can sometimes indicate tooth decay. Cavities expose the inner layers of the tooth, allowing temperature changes, bacteria, and acids to irritate the dental pulp.

Can teeth grinding cause teeth to tingle?

Yes. Bruxism, or teeth grinding, places excessive pressure on teeth and can irritate the dental pulp. Over time, grinding may wear down enamel, crack teeth, and increase tooth sensitivity or tingling.

Why do my teeth tingle after brushing?

Teeth may tingle after brushing if you brush too aggressively or use a hard-bristled toothbrush. Over-brushing can wear away enamel and expose dentin, which contains microscopic tubules connected to the tooth nerve.

Can a filling cause tooth tingling?

Yes. A new filling that is too high or an old filling that is damaged may affect your bite and irritate the tooth. This can lead to tingling, sensitivity, or discomfort when chewing.

Is tooth tingling serious?

Tooth tingling should not be ignored. It may indicate inflammation inside the tooth, enamel damage, or infection. Early dental treatment can prevent more serious problems such as pulp death or a dental abscess.

What is pulpitis?

Pulpitis is inflammation of the dental pulp, which contains nerves and blood vessels inside the tooth. Symptoms may include tingling, sensitivity, throbbing pain, or discomfort when eating hot or cold foods.

Can sensitive teeth feel like tingling?

Yes. Sensitive teeth may create a tingling or zinging sensation when exposed to cold drinks, hot foods, sweets, or acidic foods. This often occurs when enamel has worn down or gums have receded.

How do dentists treat tingling teeth?

Treatment depends on the cause. A dentist may recommend replacing a faulty filling, treating tooth decay, using fluoride treatments, fitting a night guard for grinding, or performing root canal therapy if the pulp is infected.

When should I see a dentist for tingling teeth?

You should see a dentist if the tingling persists, worsens, or is accompanied by pain, swelling, sensitivity, or difficulty chewing. Early treatment can help prevent infection and tooth loss.
