FAQs About Sensitive Teeth

Tooth Sensitivity

Why are my teeth sensitive?

Tooth sensitivity, or dentine hypersensitivity, can develop over time as a result of enamel wear and/or receding gums and can occur when the inner part of the tooth called “dentine" becomes exposed. Thousands of microscopic channels run through the dentine toward the center of the tooth, where the nerves lie. Once the dentine is exposed, certain triggers (such as a cold or hot drink) can stimulate the nerves, resulting in that characteristic short, sharp jolt of tooth sensitivity pain.

Once dentine is exposed, there is no going back, but you can get sensitivity protection by brushing with Sensodyne toothpaste twice a day, everyday.
What causes sensitive teeth to hurt?
That sharp shock, jolt, or even minor twinge of pain you feel may be caused by these common triggers below:

Cold foods or drinks

Breathing in cold air

Hot foods or drinks

Sugary foods

Sour foods

Brushing your teeth

Learn more about the symptoms of sensitivity and what can cause it.
Are sensitive teeth common?

Yes. As many as 2 in 3 people may experience dentine hypersensitivity/tooth sensitivity.¹
Can overbrushing cause sensitive teeth?

Yes, brushing too hard or too frequently can contribute to gum recession and/or enamel wear, which, over time, can expose the inner layer of your tooth, known as dentine, and can lead to sensitive teeth. Brush your teeth twice a day with a soft-bristled toothbrush.
Are sensitive teeth a sign of a more serious dental problem?

There are many different causes of tooth pain other than tooth sensitivity. For example, a cracked tooth or a cavity (tooth decay). If you are feeling any tooth pain or discomfort, the best thing you can do is visit your dentist and seek professional advice.
What can I do to help my sensitive teeth?

Switching to a daily sensitivity toothpaste, like Sensodyne, can provide ongoing relief from the symptoms of sensitivity when used twice a day, every day. Sensodyne is specially formulated for tooth sensitivity relief and is the No.1 toothpaste brand for sensitive teeth.¹

In addition, talk to your dentist about the symptoms you are experiencing. Your dentist can confirm whether or not tooth sensitivity is the cause of your tooth pain and then advise you on how to best care for sensitive teeth.

Sensodyne Ingredients

What are the ingredients in Sensodyne toothpastes?

Sensodyne products contain fluoride, which helps fight against cavities, so you can maintain healthy teeth, every day.

Learn more about all the Sensodyne toothpastes.
Does Sensodyne toothpaste have fluoride?

All Sensodyne toothpastes contain fluoride, which is a mineral that rapidly enters mineralized tissue, such as bone and developing teeth. It hardens tooth enamel, protecting against tooth decay (cavities), so you can maintain healthy teeth every day.

Learn more about the ingredients in Sensodyne and how they work to reduce tooth sensitivity.
What is stannous fluoride and how is it used in Sensodyne toothpaste?

Stannous fluoride is a type of fluoride that builds a robust layer over the exposed inner part of your tooth called dentine, acting like a shield for your sensitive teeth. This layer helps prevent triggers, like hot and cold liquids, from causing pain.

Sensodyne Complete Care and Sensodyne Rapid Relief toothpastes all contain stannous fluoride.
What is potassium nitrate and how is it used in Sensodyne toothpaste?

Potassium nitrate is a mineral that helps soothe the nerves inside your teeth, preventing triggers, like a burst of cold air or hot coffee, from causing sensitivity pain.

Sensodyne Daily Care toothpastes all contain potassium nitrate.
Does Sensodyne toothpaste contain triclosan?

Sensodyne toothpastes do not contain triclosan.
Is Sensodyne toothpaste gluten free?

Sensodyne products do not contain gluten as an ingredient. However, we cannot exclude the presence of trace amounts of gluten in these products as a result of third-party manufacturing processes because Haleon Consumer Healthcare has not tested every batch of the final products for gluten.

Enamel Erosion

What is enamel erosion?

Enamel erosion occurs when your tooth enamel, the outer, translucent protective layer of your teeth, wears away, which can cause you to experience tooth sensitivity. Enamel wear can happen as a result of teeth grinding, aggressive brushing, or an acidic diet. Once enamel wears away, it cannot grow back.

Not sure if your teeth are at risk? Let's find out if Sensodyne toothpaste is right for you.
What causes enamel wear?

Over time, frequent daily intake of acidic foods and drinks—such as fruit juices, carbonated drinks—can wear away your tooth enamel. This is also known as acid erosion. Other causes of enamel wear include teeth grinding and aggressive brushing.

To help protect your teeth against enamel erosion, talk to your dentist and use a fluoride toothpaste specially formulated to help strengthen tooth enamel.
Can enamel erosion cause sensitive teeth?

Yes. Enamel is the hard, protective surface of the tooth. Over time, if tooth enamel wears away, it exposes the inner layer known as dentine. This can cause tooth sensitivity as the protection the enamel provides to the tooth and the nerves inside is reduced. This is why, if you have enamel erosion, eating ice cream or sipping hot soup can be painful.
Why should I use a Sensodyne mouthwash?

Used with Sensodyne toothpastes and toothbrushes, Sensodyne Cool Mint Mouthwash is part of a good overall oral care plan. It is suitable for people with sensitive teeth, it has a no-alcohol formula, a mild mint taste and fluoride to help fight tooth decay.
Where can I purchase Sensodyne toothbrushes?

Sensodyne toothbrushes are available in the oral care section of most major pharmacy and grocery retailers.
Can Sensodyne be dabbed on a sensitive tooth?

Sensodyne Rapid Relief can be dabbed on for relief at 60 seconds* (when used as directed). For other Sensodyne varieties, there is no clinical evidence to support dabbing as an effective means of application.

*apply a pea-sized amount to a clean finger-tip and rub gently into each sensitive area (max twice per day) for 1 minute before brushing.
