Brushing your teeth a bit too enthusiastically
Pushing down on your toothbrush and brushing too hard won’t make your teeth cleaner, but it may wear away the protective enamel layer and lead to sensitivity. When you brush, use a gentle technique and a soft toothbrush.
Gum disease
Gum disease can cause your gums to recede, exposing the root surfaces which can trigger sensitivity.
Grinding or clenching your teeth
Grinding or clenching can wear away tooth enamel. This often happens during sleep but can also occur during the day.
Acid erosion
Acidic foods and drinks, as well as stomach acid from reflux or vomiting, can wear down enamel over time.
Chipped, broken or decayed teeth
Damage or decay can expose the inner part of the tooth, making it more sensitive.
Recent dental work
Procedures such as fillings, crowns or even a routine scale and clean may cause temporary sensitivity, which usually settles on its own.
How to avoid sensitive teeth
- Brush and floss regularly and make sure you are brushing correctly – if you’re not sure, ask your dentist.
- Always use a soft toothbrush and consider using toothpaste for sensitive teeth as part of your daily routine.
- When you eat or drink something acidic, rinse your mouth with water, chew sugar-free gum and wait at least 60 minutes before brushing.
It’s important to remember that some tooth sensitivity can be linked to more serious problems, including tooth decay, a fractured filling, a cracked tooth or issues affecting the nerve of the tooth. If you are experiencing sensitivity, it’s best to let your dentist know.
