Does a sip of cold water make you wince? Tooth sensitivity can make everyday things like drinking, eating, or brushing uncomfortable. It may happen when tooth enamel is worn or when roots become exposed, but sensitivity can have other causes too. A dental exam can help identify what is behind it.

If you are looking for help with tooth sensitivity in Mississauga, here are common causes and steps to consider.

What does tooth sensitivity feel like?

Sensitivity may feel like a quick, sharp discomfort when you have something hot, cold, sweet, or acidic, or when cold air reaches your teeth. Some people notice it while brushing or when pressure is applied to a tooth.

The sensation can have different causes, so it is best not to assume that sensitivity is harmless or try to diagnose it yourself.

Common causes of sensitive teeth

Tooth sensitivity can be associated with several conditions, including:

• Worn enamel: Enamel protects the more sensitive layer beneath it. Acid erosion or wear may leave that layer more exposed.
• Receding gums: When gums recede, the roots may become exposed and more sensitive.
• Tooth decay or a crack: A cavity or crack can cause discomfort that feels like sensitivity.
• Gum disease: Changes in the gums can expose sensitive parts of a tooth.
• Worn fillings: Older dental work may contribute to sensitivity.
• Clenching or grinding: Repeated pressure on teeth can wear their surfaces.

These are possibilities, not a diagnosis. Your dentist can examine the tooth and gums and recommend next steps based on what they find. Learn more from the Ontario Dental Association’s guide to tooth sensitivity.

What can you do at home?

While you arrange an appointment or follow your dental team’s advice, you can try a few gentle steps:

• Use a soft-bristled toothbrush and brush gently.
• Ask your dentist whether a desensitizing toothpaste or another fluoride product is suitable for you.
• Reduce acidic foods and drinks if they seem to trigger discomfort.
• Let your dentist know when the sensitivity started and what brings it on.

Avoid brushing harder over a sensitive area. If a product or change to your routine makes the discomfort worse, stop and ask your dental team what to do.

When should you contact a dentist?

Tell your dentist if your teeth are sensitive to hot, cold, or sweet foods and drinks. Contact the office promptly if the tooth is also sensitive to pressure, the pain lasts longer than an hour, your gums around it change colour, or symptoms do not improve after using desensitizing toothpaste for a few weeks.

A dental exam can help assess the teeth, gums, existing dental work, and signs of clenching or grinding. The right timing for visits depends on your individual oral health needs, general health, and lifestyle. The Ontario Dental Association explains what happens during a general dental examination.
