Causes of Tooth Sensitivity and Effective Solutions

Have you ever felt a sharp pain in your teeth while drinking cold water or hot tea? Do sweet foods or cold drinks make your teeth hurt? If yes, you may have sensitive teeth.

Tooth sensitivity is a common problem. It can make eating, drinking, and brushing your teeth painful. However, the right treatment can reduce the pain and help protect your teeth.

At Wandsworth Town Dental Practice, we understand how sensitive teeth can affect your daily life. In this guide, we explain the common causes of tooth sensitivity and how to reduce the pain.

What Is Tooth Sensitivity?

Tooth sensitivity happens when the inner part of your tooth becomes exposed. As a result, hot, cold, sweet, or acidic foods and drinks can cause a sudden, sharp pain. The pain usually lasts for a few seconds.

Your teeth have a hard outer layer called enamel. Under it is a softer layer called dentine. Dentine has tiny channels that lead to the nerves inside your teeth.

When enamel wears away or your gums pull back, these tiny channels become exposed. As a result, your teeth may become more sensitive to hot, cold, or sweet foods and drinks.

Common Causes of Tooth Sensitivity

Several dental problems and everyday habits can cause sensitive teeth. Therefore, it is important to understand the common causes. Here are some of the main reasons why tooth sensitivity occurs.

1. Worn Tooth Enamel

Tooth enamel protects your teeth from damage. However, acidic foods and drinks can slowly weaken this protective layer over time.

Brushing too hard can also wear down enamel. Once enamel becomes thinner, the sensitive layer underneath may become exposed.

What can help? Use a soft-bristled toothbrush and fluoride toothpaste. Also, try to drink fewer acidic drinks, such as fizzy drinks and fruit juices.

2. Receding Gums

Your gums protect the roots of your teeth. However, gum disease, ageing, or brushing too hard can cause your gums to pull away from your teeth.

This exposes the roots of your teeth, which do not have the same hard enamel cover as the visible parts. As a result, your roots may become sensitive to hot and cold foods and drinks.

What can help? Brush your teeth gently and keep your mouth clean. If your gums are pulling away from your teeth, visit your dentist to find the cause and get the right treatment.

3. Tooth Decay and Cavities

Tooth decay happens when bacteria in your mouth produce acids that damage your teeth. Over time, this damage can create small holes called cavities.

Cavities can make your teeth hurt when you eat sweet foods or drink something hot or cold. You may also feel pain when chewing food.

What can help? Visit your dentist for a check-up. Depending on the damage, your dentist may recommend a filling or another suitable treatment to protect your tooth.

4. Cracked or Damaged Teeth

A cracked tooth can expose the sensitive layers inside your tooth. You may feel pain when biting food or eating something hot or cold.

Sometimes, small cracks are difficult to see without a dental examination.

What can help? Visit your dentist if you think you have a cracked tooth. Your dentist will check the damage and suggest the right treatment to protect your tooth.

5. Brushing Too Hard

Moreover, brushing your teeth too hard can damage your gums and gradually wear away the enamel near the gum line. As a result, your teeth may become more sensitive.

Additionally, using a hard-bristled toothbrush can increase the risk of damage. As a result, your teeth may become more sensitive over time.

To reduce sensitivity, use a soft-bristled toothbrush and brush gently in small, circular movements. Additionally, brush your teeth twice a day with fluoride toothpaste.

6. Teeth Grinding

Some people grind or clench their teeth while sleeping or when they feel stressed. This habit is called bruxism.

Over time, grinding your teeth can wear away enamel and put extra pressure on your teeth. As a result, you may have sensitive teeth, jaw pain, or headaches.

What can help? Talk to your dentist if you grind your teeth. They may suggest a custom-made night guard to protect your teeth while you sleep.

7. Recent Dental Treatments

Some people have temporary tooth sensitivity after dental treatments, such as professional teeth whitening, fillings, or other procedures.

This sensitivity usually gets better after a short time. However, do not ignore severe pain or sensitivity that does not go away.

What can help? Follow your dentist’s aftercare advice. If the sensitivity does not improve or gets worse, contact your dentist.

Effective Solutions for Tooth Sensitivity

The right treatment depends on what is causing your tooth sensitivity. Fortunately, there are several effective treatments available. As a result, they can help reduce pain and discomfort.

1. Use Toothpaste for Sensitive Teeth

Desensitising toothpaste can help reduce tooth sensitivity when used regularly. Some ingredients block tiny channels in the teeth, while others help calm the nerves and reduce pain.

Choose a fluoride toothpaste made for sensitive teeth. Follow the instructions on the pack. If you are unsure which toothpaste to use, ask your dentist for advice.

2. Brush Gently with a Soft Toothbrush

Good brushing habits help keep your teeth and gums healthy. However, brushing harder does not make your teeth cleaner.

Use a soft-bristled toothbrush and brush gently. Brush your teeth for about two minutes, twice a day, using fluoride toothpaste.

Avoid brushing your teeth right after eating or drinking acidic foods and drinks. Instead, wait 30 to 60 minutes to protect your softened enamel.

3. Reduce Acidic Foods and Drinks

Acidic foods and drinks can slowly weaken your tooth enamel. These include fizzy drinks, citrus fruits, fruit juices, and foods containing vinegar.

You do not need to avoid all acidic foods. Instead, try to have them less often and drink acidic drinks with meals when possible.

Also, rinse your mouth with water after eating acidic foods or drinking acidic drinks.

4. Get Professional Fluoride Treatment

Fluoride helps strengthen tooth enamel and protect your teeth from decay. If you have sensitive teeth, your dentist may recommend a professional fluoride treatment to help reduce sensitivity.

Your dentist may also recommend other products to reduce tooth sensitivity, depending on your dental needs.

5. Treat Cavities and Cracked Teeth

Toothpaste alone cannot fix a cavity or a damaged tooth. Therefore, if sensitivity is caused by tooth decay or a crack, you may need dental treatment.

Your dentist may suggest a filling, crown, or another treatment, depending on the condition of your tooth.

6. Treat Gum Problems

If gum disease or receding gums cause sensitivity, your dentist will check your gums and suggest the right treatment.

Treatment may include professional teeth cleaning, better oral care, or other gum treatments if needed.

7. Consider a Night Guard for Teeth Grinding

If you grind your teeth while sleeping, your dentist may recommend a custom-made night guard to protect your teeth from further damage.

Your dentist can check if you grind your teeth and tell you whether a night guard would help protect them.

When Should You See a Dentist for Tooth Sensitivity?

Mild tooth sensitivity may improve with simple changes to your oral care routine. However, lasting or severe sensitivity may be a sign of a dental problem that needs treatment.

Book a dental appointment if you experience:

• Tooth sensitivity that lasts for several days or keeps returning.
• Sharp pain when biting or chewing.
• Sensitivity in one specific tooth.
• Visible holes, cracks, or damage to a tooth.
• Swollen, bleeding, or receding gums.
• Tooth pain that affects your sleep or daily activities.

Seek urgent dental advice if you develop severe pain or facial swelling. If swelling affects your breathing or swallowing, seek emergency medical care immediately.

How Can You Prevent Tooth Sensitivity?

Although you cannot prevent every cause, good oral care can help lower your risk.

Follow these simple tips to protect your teeth:

• Brush twice daily with fluoride toothpaste.
• Use a soft-bristled toothbrush.
• Floss or clean between your teeth every day.
• Limit frequent sugary and acidic foods and drinks.
• Avoid brushing too hard.
• Wear a suitable mouthguard if recommended for sports or teeth grinding.
• Attend regular dental check-ups.
• Seek dental advice when sensitivity starts or continues.

Early dental care can help identify problems before they become more serious.
