Tooth sensitivity can come on suddenly and make simple things like eating ice cream or drinking hot tea feel uncomfortable. It often feels like a sharp twinge or a dull ache, and may be triggered by cold, heat, sweet foods or even brushing.
If you are experiencing sensitivity, it is important to see a dentist to rule out any serious underlying issues. However, while you wait for your appointment, there are a few things you can do at home to reduce discomfort and protect your teeth from further irritation.
Here are some of the most effective home remedies for sensitive teeth, and what to know about when symptoms might need professional treatment.
What Causes Tooth Sensitivity?
Tooth sensitivity happens when the protective layer of enamel on your tooth wears away, exposing the dentine underneath. This layer contains tiny tubes that lead to the nerve, so when it is exposed, temperature changes and certain foods can trigger discomfort.
Common causes include:
- Brushing too hard or using a hard bristle toothbrush
- Tooth enamel erosion from acidic foods or drinks
- Gum recession from gum disease
- Tooth grinding or clenching
- Tooth decay, chips or cracks
- Recent dental work such as whitening or fillings
If your sensitivity lasts longer than a few days or becomes more intense, it is important to book a dental appointment as soon as possible.
Home Remedies for a Sensitive Tooth
While home remedies do not treat the underlying cause, they can help reduce symptoms in the short term. These are safe and commonly recommended ways to soothe a sensitive tooth at home.
1. Use a Desensitising Toothpaste
Choose a toothpaste designed for sensitive teeth. These formulas contain ingredients that block pain signals from the tooth to the nerve. Brush twice daily using gentle pressure and avoid rinsing immediately after brushing to allow the active ingredients to work longer.
2. Rinse with Warm Salt Water
Salt water is a natural antibacterial and can help reduce inflammation. Mix half a teaspoon of salt into a glass of warm water and rinse your mouth for thirty seconds, two to three times a day.
3. Avoid Acidic and Sugary Foods
Cutting back on citrus fruits, fizzy drinks, wine and sweets can help prevent further enamel wear and ease sensitivity. Try to wait at least thirty minutes after eating acidic foods before brushing.
4. Apply a Cold Compress
If your sensitivity comes with swelling or discomfort in the jaw, apply a cold compress to the outside of your cheek for ten to fifteen minutes at a time to ease inflammation.
5. Maintain a Gentle Oral Care Routine
Switch to a soft bristle toothbrush and avoid brushing too aggressively. Over time, hard brushing can wear down enamel and contribute to gum recession, making sensitivity worse.
6. Use a Fluoride Mouthwash
Fluoride helps strengthen tooth enamel and can make your teeth less sensitive to triggers. Choose an alcohol-free mouthwash for sensitive teeth and use it once or twice daily.
When to See a Dentist
While these home remedies may help relieve symptoms temporarily, they are not a long term solution. Ongoing sensitivity could be a sign of something more serious, such as:
- Tooth decay or infection
- A cracked or fractured tooth
- Gum disease
- An old filling or crown that needs replacing
If your sensitivity continues for more than a few days, becomes more intense, or begins to interfere with eating or sleeping, it is time to seek professional advice.
At Tooth Club, our clinicians can assess your symptoms quickly and provide safe, lasting solutions. This may include dental sealants, fluoride varnishes, fillings or other treatments designed to protect your teeth and relieve discomfort.
