Tooth sensitivity is a common condition that typically occurs when consuming very hot or cold food and drinks. However, it's not just limited to what you eat or drink. There are several other underlying factors, particularly dental issues, that can trigger tooth sensitivity. Curious about the causes and remedies for sensitive teeth? Read on to find out more.

Causes of Sensitive Teeth

Tooth sensitivity often arises when the soft inner layer of the tooth, called the dentin, is exposed. This usually happens due to enamel erosion or gum recession. When this occurs, external stimuli—like hot, cold, or sweet foods—can reach the nerves inside the tooth, causing a sharp, tingling sensation.

Here are some common causes of sensitive teeth:

Brushing Too Hard

Using a hard-bristled toothbrush or brushing with excessive force can wear down the enamel on your teeth. This leads to the exposure of the underlying dentin, making the teeth more sensitive. Over time, this habit can also cause gum recession, further exposing the tooth roots. To avoid this, consider switching to a soft-bristled toothbrush and adopting a gentler brushing technique.

Gum Recession

Gum recession, also known as gingival recession, occurs when the gums pull back from the surface of the teeth, revealing the tooth roots. When the roots are exposed, they are more susceptible to sensitivity. Treatment options for receding gums include pain relievers, professional cleaning (scaling), or even orthodontic procedures to address the issue.

Gum Disease

Gum disease, or periodontal disease, involves inflammation and infection of the gums and surrounding bone tissue that supports the teeth. This condition is often the result of poor oral hygiene. In addition to tooth sensitivity, symptoms of gum disease can include bad breath, loose teeth, swollen or bleeding gums. Early treatment is essential to prevent further complications.

Cavities

Cavities are a result of tooth decay, where the outer layer of the tooth wears away, causing damage to the tooth tissue. Cavities are often caused by plaque buildup due to insufficient oral care, making the teeth more prone to sensitivity.

Cracked Tooth Crown

While cracks in the tooth crown may not always be visible, they can still cause considerable pain and sensitivity. Cracked teeth allow bacteria and plaque to enter the tooth's pulp (root canal), leading to inflammation. Additionally, these cracks can expose the tooth nerves, contributing to the sensation of pain.

Sinus Infection

A sinus infection can cause pain in the teeth and jaw, as the inflamed sinus cavities can put pressure on the nerves in the teeth. The fluid buildup in the sinuses from the infection may exacerbate this discomfort, making it feel like the teeth themselves are sensitive.

Recent Dental Procedures

After undergoing dental treatments like scaling, fillings, or restorative work, some people may experience tooth sensitivity. This is typically a temporary issue and should subside within 4 to 6 weeks as the teeth adjust.

Managing Tooth Sensitivity

Tooth sensitivity may lessen over time without requiring special treatment. However, if the sensitivity is linked to a dental problem, such as cavities, cracks, or gum disease, professional care is necessary.

Several remedies can help alleviate discomfort, including:

• Use toothpaste formulated for sensitive teeth.
• Consider fluoride toothpaste and mouthwash for added protection.
• Maintain good oral hygiene by brushing, flossing, and rinsing regularly.
• Avoid consuming overly acidic, hot, or cold foods and drinks that can trigger sensitivity.
• Steer clear of teeth grinding, as it can exacerbate sensitivity.

If these methods don’t provide relief, it’s advisable to consult a dentist. For added convenience, you can also use the consultation service on the Ai Care app, available for download on both the App Store and Play Store.
