Tooth sensitivity is a sudden, sharp, and uncomfortable pain in the teeth that usually lasts for a few seconds. It occurs when the teeth are exposed to stimuli such as hot or cold drinks or foods, or even just cold air.
It can be caused by enamel erosion or gum recession, which exposes the dentin layer containing tiny channels connected to nerves. A person may experience sensitivity in a single tooth or a group of teeth, and it may be temporary or persistent.
What is tooth sensitivity
Tooth sensitivity, also known as dentin sensitivity, is a feeling of discomfort and sharp pain in the teeth when exposed to external stimuli such as hot or cold drinks or foods. The pain disappears once the stimulus is removed.
Symptoms of tooth sensitivity
The primary symptom of tooth sensitivity is sharp pain when exposed to stimuli. The pain may be localized to a single tooth or a group of teeth. Other common symptoms include:
- Pain when consuming hot or cold foods or drinks.
- Pain when breathing cold air. The pain is sudden and brief, disappearing once the trigger is removed.
- Pain may occur when eating sugary or acidic foods.
- Pain may also be felt when brushing or flossing.
What are the causes of tooth sensitivity
Tooth sensitivity occurs when the enamel layer is thin or when the dentin layer is exposed due to enamel erosion. This causes pain when exposed to certain stimuli. Other causes include:
- Brushing teeth too vigorously or using a hard-bristled toothbrush.
- Overuse of whitening toothpaste or professional teeth whitening.
- Overuse of mouthwash.
- Frequent consumption of acidic foods and drinks.
- Cavities or a broken tooth.
- Gum recession or exposed tooth roots.
- Teeth grinding (bruxism).
- Circumcision or clenching of the teeth after certain dental procedures, especially after fillings or deep cleanings.
Treating Tooth Sensitivity at Home
Treatment for tooth sensitivity depends on identifying the cause and determining the appropriate treatment. The treating dentist will prescribe special toothpastes and mouthwashes for sensitive teeth, as well as topical medications to reduce tooth sensitivity.
They will also prescribe mouthguards if the cause is teeth grinding (bruxism), to provide a protective layer and alleviate pain. They may also prescribe sealants or fillings to protect exposed roots.
Deep cleaning to remove tartar and root canal treatment are also recommended in severe cases. The dentist will also advise using a soft-bristled toothbrush and reducing the consumption of extremely hot or cold foods and drinks.
Medications for Treating Tooth Sensitivity
- Myogesic tablets.
- Norgesic tablets.
- Lister Mix Plus mouthwash.
- Sensodyne Fluoride.
How to Prevent Tooth Sensitivity
Tooth sensitivity can be prevented by following these guidelines, which help protect the enamel:
- Brush your teeth with a soft-bristled toothbrush using gentle circular motions to avoid abrading the enamel.
- Brush twice a day, especially before bed, with fluoride toothpaste.
- Reduce your intake of acidic foods and drinks, which increase enamel erosion.
- Avoid excessive teeth whitening to prevent sensitivity afterward.
- Visit your dentist regularly, at least twice a year.
- Quit smoking and abstain from alcohol.
Frequently Asked Questions
What is the difference between nerve pain and tooth sensitivity
The main difference is that tooth sensitivity is a sharp, short-lived pain that disappears quickly once the trigger is removed. Nerve pain, on the other hand, is a continuous pain that may occur spontaneously and is not easily relieved.
How long does tooth sensitivity pain last
In some cases, sensitivity disappears within a few days or weeks, while in others, it may persist for longer periods.
What is the best mouthwash for sensitive teeth
The best mouthwashes are those containing ingredients like potassium fluoride or potassium citrate to seal dentin canals and provide long-lasting protection.
Is salt water helpful for sensitive teeth
Rinsing with salt water is a natural remedy to reduce pain and inflammation, helping to clean and soothe the mouth.
