Sensitive teeth FAQ: whitening, fillings, pregnancy and more

Tooth sensitivity raises a lot of questions. Here are clear answers to some of the most common ones we hear.

Can teeth whitening make my teeth sensitive?

Yes, temporary sensitivity is a common side effect. It usually settles within a few days. If you're considering whitening, our teeth whitening guide explains what to expect, and we can tailor the approach for sensitive teeth.

Is it normal for a tooth to be sensitive after a filling or crown?

Mild sensitivity to cold or biting pressure for a short time after treatment is fairly common. If it's getting worse or hasn't eased after a few weeks, let us know so we can take a look.

Does sensitivity mean I have a cavity?

Not always. Exposed dentin from gum recession or enamel wear can cause the same zing. Only an exam can tell the difference, sometimes with an X-ray.

Will sensitivity go away on its own?

Sometimes, especially if the cause was temporary, like recent whitening. If it's caused by recession or wear, it tends to stick around until you address the cause.

Why is only one tooth sensitive?

A single sensitive tooth can point to a local issue, such as a small crack, a worn spot or an older filling. It's a good reason to book a visit.

Do I need a root canal for sensitive teeth?

Usually not. Most sensitivity is managed with simpler steps. A root canal is considered when a nerve is inflamed or infected, often with lingering pain or swelling.

When should I see a dentist?

Book a visit if pain lingers after cold, wakes you at night, or affects one tooth in particular. Our family dentistry team in South Surrey and White Rock is happy to help.
