Dental hypersensitivity is one of the most common reasons why patients visit their dentist, but despite its prevalence, many sufferers have little idea how to treat their condition.

Luckily, treating sensitive teeth is usually a simple and inexpensive process. Thanks to the wide array of treatments available over the counter in pharmacies and even supermarkets, treating the condition is now easier than ever. If a visit to the dentist is required, the problem can often be resolved in as little as two visits. Here are four treatments you can try to help minimise tooth sensitivity.

1. Change Your Diet and Tooth-Care Habits

Many cases of sensitive teeth are caused by tooth erosion, which occurs when the layer of enamel protecting your teeth wears away. Often, treating sensitive teeth is as easy as stopping tooth erosion in its tracks.

The main cause of enamel decay is excess acids, which can arise due to poor diet or excessive consumption of beverages such as soft drinks and juice. Regular brushing can help clean away acids, but be careful not to brush too hard, as harsh brushing can also wear away your tooth enamel.

Another common cause of enamel decay is the excessive use of at-home teeth whitening products. Overusing these products can permanently strip your enamel away, leaving your teeth exposed to sensitivity triggers such as hot drinks or cold foods.

2. Use Special Toothpaste

Desensitising toothpastes work by shielding the nerves buried deep in your teeth from outside triggers. These toothpastes are easily available from the dental care aisle at your local supermarket, and you should use them for at least a month to see reliable results. Dentists generally recommend calcium-based toothpastes, as they usually work faster.

These toothpastes will help treat the symptoms of sensitive teeth but not the cause, so if you find that you continue to experience sensitivity or pain after a month of use, a visit to the dentist might be in order.

3. Try a Prescription Gel

If at-home treatments fail, prescription desensitising gels and mouthwashes are another way to manage sensitive teeth. Your dentist may choose to apply fluoride gel to your teeth themselves, or your dentist could give you a bottle to take and use at home.

While it is not possible to restore tooth enamel once it has been lost, fluoride helps to remineralise the remaining enamel so it can defend against sensitivity triggers. The active ingredients in fluoride gels have been clinically proven to relieve sensitivity, and in many cases, all that is required is one or two in-office applications.

4. Get Dental Surgery to Protect Sensitive Spots

Unfortunately, if the underlying cause of your sensitive teeth is more serious than simple tooth erosion, your dentist may recommend a more permanent treatment to resolve the problem. One cause of sensitive teeth that may not be cured by the previous three treatments is an exposed root due to receding gums.

One solution to this condition is a surgical gum graft. This is a relatively minor procedure that can usually be undertaken in your dentist or periodontist’s office, and it involves covering the exposed root with gum tissue taken from another part of the mouth. The procedure does cause some pain, but this normally vanishes a few days after surgery.

Your dentist may also recommend a root canal if the sensitivity is particularly serious. This treatment requires more than one appointment.

Sensitive teeth can be uncomfortable and painful, especially if eating or drinking foods you love often triggers your sensitivity! If lifestyle changes and over-the-counter treatments do not alleviate your tooth sensitivity, don’t delay. Make an appointment with the friendly staff at Dental Smile Clinic today.

Frequently Asked Questions About Sensitive Teeth

What causes sensitive teeth?

Sensitive teeth are commonly caused by worn enamel, exposed tooth roots, gum recession, tooth grinding, cavities, cracked teeth, or acidic foods and drinks that weaken enamel over time.

Why do my teeth hurt when eating cold or hot foods?

Pain from hot, cold, sweet, or acidic foods usually happens when dentin becomes exposed. Dentin contains tiny tubules that connect directly to the nerves inside the tooth.

Can tooth sensitivity go away naturally?

Mild tooth sensitivity may improve when enamel is protected and triggers are avoided. However, ongoing or worsening sensitivity should be assessed by a dentist to identify the underlying cause.

What is the best toothpaste for sensitive teeth?

Desensitising toothpaste containing fluoride, calcium compounds, potassium nitrate, or stannous fluoride is commonly recommended to help block nerve signals and reduce sensitivity.

How long does sensitive toothpaste take to work?

Most desensitising toothpastes require consistent use for at least 2–4 weeks before noticeable improvement occurs.

Can brushing too hard cause tooth sensitivity?

Yes. Aggressive brushing and hard-bristled toothbrushes can wear down enamel and contribute to gum recession, both of which can increase tooth sensitivity.

Do whitening products make teeth sensitive?

Some at-home whitening products can temporarily or permanently increase tooth sensitivity, especially when overused or used incorrectly.

What foods should I avoid if I have sensitive teeth?

People with sensitive teeth should limit acidic foods and drinks such as soft drinks, citrus fruits, wine, sports drinks, and sugary snacks that can weaken enamel.

When should I see a dentist for sensitive teeth?

You should see a dentist if sensitivity lasts longer than a few weeks, becomes severe, interferes with eating or drinking, or is accompanied by swelling or tooth pain.

Can gum recession cause sensitive teeth?

Yes. Receding gums expose the tooth roots, which do not have protective enamel. This can make teeth highly sensitive to temperature and pressure changes.

What dental treatments help sensitive teeth?

Dentists may recommend fluoride treatments, desensitising gels, bonding, gum grafting, or root canal treatment depending on the severity and cause of the sensitivity.

Is tooth sensitivity a sign of a cavity?

Sometimes. Tooth sensitivity can indicate tooth decay, cracks, worn fillings, or infection, so professional evaluation is important if symptoms persist.

Can fluoride help sensitive teeth?

Yes. Fluoride helps strengthen and remineralise enamel, reducing the tooth’s response to sensitivity triggers.

Are sensitive teeth permanent?

Not always. Many cases improve with proper oral care, dietary changes, and professional treatment. However, untreated enamel loss or gum recession may require ongoing management.

How can I prevent tooth sensitivity?

Use a soft-bristled toothbrush, avoid aggressive brushing, limit acidic foods and drinks, wear a night guard if you grind your teeth, and maintain regular dental check-ups.
