What causes sensitive teeth?
There are a few possible causes of sensitive teeth. Some are underlying issues that need to be addressed, but others can cause tooth sensitivity to just come and go, apparently at random. Sensitive gums and teeth are most common in people aged 20-40 years old and women are more likely to be affected than men.
Could any of the following sensitive teeth causes be the reason for your discomfort?
- Worn down enamel can cause very sensitive teeth. Enamel is the solid layer on the outside of your teeth that protects the dentine and tooth nerves underneath. If you start to wear out and lose this, you will find your tooth is sensitive to heat and cold.
- Exposed tooth roots mean the part of your tooth with the least protective enamel is exposed, so there’s a greater chance of sensitivity.
- Cavities are another way your dentine and tooth nerves can become exposed, giving you sore teeth and sensitivity.
- A cracked or chipped tooth exposes the middle of your tooth and sometimes even nerves. We have a full guide on how to deal with cracked and chipped teeth for lots more information.
- A worn out or ill-fitting filling will expose an old cavity to the same problems of teeth sensitivity as before you got the filling.
- Gum disease exposes the teeth roots, which don’t have any protective enamel, thereby causing the teeth to become sensitive.
- Gum erosion is a normal process – nearly 90% of people over 65 experience it – and it will increase the chances of having teeth sensitive to cold and heat.
Any of these factors can make the tooth sensitive to heat, cold, sugar and acid.
Treatments for sensitive teeth
Depending on the cause of your sensitive gums and teeth, there are a range of treatment options to try. In certain cases, home remedies or store-bought products can be a quick, easy, and effective way to stop sensitive teeth. On the other hand, you may need dental treatment to fix the underlying cause before your tooth sensitivity develops into a full-blown toothache.
Here is a breakdown of some of the treatments that might be suitable for you.
Natural home remedies for sensitive teeth
When your teeth are suddenly sensitive, you might look around the kitchen and think, “What do I have lying around that helps sensitive teeth?” Well, there are a few options that you can try at home before spending money on any medicines.
- Oil pulling involves swishing oil, such as coconut oil, around your mouth. It’s been proven to reduce gum disease and so could help protect against sensitive teeth.
- Salt water rinses can help to relieve sensitivity, since salt has antiseptic properties and helps to reduce inflammation. Try adding a teaspoon of salt to a cup of hot water, stir until it dissolves, allow it to cool, then rinse around your mouth to get some quick sensitive teeth pain relief. As an added bonus, salt water has been noted to reduce plaque build-up.
- Honey and warm water rinses work in a similar way to salt water ones. Honey is known to have antiseptic and anti-inflammatory qualities that can help with sensitive teeth pain.
- Clove oil gel is a well-known home remedy for toothache and scientists have confirmed it too. It might not stop sensitive teeth pain immediately, but the natural pain-killing action should kick in after around 5-10 minutes.
Mouthwash and toothpaste for sensitive teeth
Whether you want to treat sensitive front teeth or back teeth, you’ll find a range of products in your local supermarket or chemist that claim to cure sensitive teeth pain. These are usually in the form of toothpastes and mouthwashes which contain extra fluoride. Here’s what to look for:
Mouthwash can help with sensitive teeth symptoms in the long term. Specially formulated mouthwash for sensitive teeth like Listerine Advanced Defence Sensitive usually contains fluoride. Use it twice a day but at different times to when you brush.
Toothpaste for sensitive teeth can be really effective as a long-term treatment; some people report improvement in sensitive gums and teeth within a few days. Make sure that you choose a toothpaste with fluoride in it, as this is a key ingredient to strengthening tooth enamel. Look for products with 1350 – 1500 ppm of fluoride to get the best effect.
One of the best toothpastes for sensitive teeth in the UK is Sensodyne Sensitive Toothpaste Daily, from a brand which specialises in treating this problem. It gets really good reviews and some users say that it improved their really sensitive teeth within a couple of days.
Another option for those who want a fluoride-free sensitive teeth toothpaste is Colgate Sensitive Pro-Relief. It contains arginine and calcium carbonate to rebuild enamel and help physically block any pain you might be experiencing.
Your dentist may prescribe you a toothpaste with a higher fluoride concentration to relieve sore teeth, or apply a concentrated fluoride varnish to protect and strengthen teeth. Read about some other ways to remineralize and strengthen enamel in our separate article.
When to visit a dentist
The pain from sensitive teeth should only be fleeting, rather than long-lasting or constant. When you have teeth sensitive to sugar, acid, or extreme temperatures, the pain will only occur if your teeth come into contact with these things.
If the pain lasts for a long time after these triggers, or isn’t associated with anything in particular that you eat or drink, there’s a chance that a more serious problem is causing your sensitive teeth pain. In this case, it’s best to have a dental checkup and mention your concerns.
Until your appointment, you can manage any pain by taking regular painkillers (if they are normally suitable for you). Check out our guide to toothache for more information about what might be causing the pain, what treatments are available, and how you can manage your pain at home.
How to fix sensitive teeth for good
If you’re looking for a complete cure for sensitive teeth, your dentist will probably have the answer. Depending on what’s causing your teeth to be sensitive, they may recommend one of these treatments:
Preventing tooth sensitivity
We’ve discussed how to help sensitive teeth, but did you know it’s also preventable? A major culprit for wearing away enamel and causing cavities is your diet. By using a straw for sugary or acidic drinks like fizzy drinks and fruit juice, you can minimise damage to your teeth. Take a metal straw wherever you go so you’re always prepared.
Another big reason you might have sensitive teeth is if you aren’t brushing correctly. You should use a soft or medium brush in a circular or up-and-down motion (not side-to-side), and avoid harsh or abrasive toothpastes.
Alternatively, consider investing in an electric toothbrush for your sensitive teeth. An electric toothbrush can help you brush correctly, meaning you’re much less likely to wear away your enamel and develop cavities. Our article all about electric toothbrushes can help you choose the right one for your needs.

Frequently asked questions
Why are my teeth so sensitive?
Sensitive gums and teeth are caused by the wearing away of the hard, enamel coating of your teeth. If the sensitivity feels quite extreme you might have a cavity, infection or gum disease. Your dentist will be able to check your teeth and identify any underlying problems that need to be treated.
How do I get rid of sensitive teeth?
You can decrease how sensitive your teeth are by using toothpastes and mouthwashes designed to protect and strengthen your tooth enamel. For a complete cure you will need to visit a dentist for bonding, a gum graft, a filling, or possibly root canal treatment.
Why do I have sensitive teeth in early pregnancy?
It is completely normal to have sensitive teeth in pregnancy. Due to changes in hormones your teeth become more susceptible to plaque and this makes gum disease more likely, causing sensitivity. The good news is that dentistry is free on the NHS for pregnant women and those who have given birth in the last year, so visit a dentist to make sure your teeth stay healthy.
Will I get sensitive teeth from whitening products?
It is possible to develop sensitive teeth after whitening them, either with a home kit or at the dentist. However, certain whitening kits like Smile Avenue are specially formulated to be gentle on teeth, so you might want to start there. You can also start by using the product for less than the recommended time, and build it up slowly to see how your teeth feel.
I have a sensitive tooth after a filling, why?
A sensitive tooth after a filling isn’t uncommon and it should subside by itself after a few days. The most likely reason for the sensitivity is that a nerve ending in the tooth has been disturbed. After it has had time to heal, it should feel normal again. If you continue to experience sensitivity for more than two weeks after getting a filling then contact your dentist.
The best thing for sensitive teeth is to follow correct brushing and general care routines. This includes brushing regularly and correctly (using a toothpaste with at least 1350 ppm of fluoride), flossing, and using mouthwash for sensitive teeth every day. Keep up with regular dentist visits so they can spot cavities or gum problems early on and offer you the most appropriate treatment.
