Tooth sensitivity can cause a short, sharp discomfort when teeth are exposed to cold, heat, sweet foods, acidic drinks or brushing. It can have several causes, and persistent or new sensitivity should not automatically be assumed to be harmless. A dental assessment can help identify the cause and guide care.
Sensitivity may occur when the protective enamel wears down or when gums recede and expose the root surface. Other possible causes include tooth decay, a cracked or damaged tooth, worn fillings, recent dental treatment or irritation from brushing too hard. The pattern and duration of symptoms can help your dentist decide what to examine.
Do not rely on sensitivity alone to diagnose a problem. If discomfort is persistent, worsening, localised to one tooth, or triggered by biting, arrange a dental assessment.
Use a soft-bristled toothbrush and brush gently with fluoride toothpaste. A toothpaste designed for sensitive teeth may help some people when used regularly according to its label. Avoid aggressive brushing and consider limiting frequent acidic drinks; after acidic foods or drinks, rinse with water and wait before brushing.
These measures do not replace dental care when sensitivity is caused by decay, a crack or another condition that needs treatment. Do not place aspirin or other medicines directly on the tooth or gum.
Arrange an appointment if sensitivity persists, returns frequently, affects one particular tooth, or comes with pain when chewing, a visible crack, a damaged filling or gum changes. Seek prompt dental advice for severe or worsening pain or swelling. Facial swelling with difficulty breathing or swallowing requires emergency medical care.
It can be one possible cause, but sensitivity can also relate to exposed roots, enamel wear, cracks or other conditions. A dental examination is needed to identify the cause.
Some products need regular use before you notice a difference. Follow the product directions and ask your dentist if symptoms persist or worsen.
Continue gentle brushing with a soft-bristled toothbrush. Avoiding the area can allow plaque to build up; ask your dentist for personalised brushing advice.
Whitening can cause temporary sensitivity in some people. If you already have sensitive teeth, speak with a dentist before whitening so possible causes can be assessed and suitable options discussed.
Arrange a dental assessment to discuss your symptoms and possible causes with Dr Ruba Masaadeh in Amman.
