Tooth sensitivity can be one of the most uncomfortable dental issues, causing sharp pain or discomfort when eating hot, cold, sweet, or acidic foods. If you suffer from sensitive teeth, you’re not alone—many people experience some degree of tooth sensitivity at some point in their lives. But the good news is, sensitive teeth can often be treated, and there are steps you can take to prevent the discomfort from returning. In this blog, we’ll explore the causes of tooth sensitivity, how a Perth dentist can help fix it, and prevention tips to keep your smile comfortable and pain-free.
What Causes Tooth Sensitivity?
Tooth sensitivity occurs when the protective layer of enamel on your teeth wears down, exposing the underlying layer of dentin. This dentin contains microscopic tubes that lead to the nerves inside the tooth. When the dentin is exposed, hot, cold, or sweet foods and drinks can trigger pain or discomfort. Here are some common causes of tooth sensitivity:
1. Worn-Down Enamel:
The most common cause of tooth sensitivity is the gradual erosion of enamel, the hard, protective outer layer of the tooth. This can happen due to poor oral hygiene, frequent consumption of acidic foods and drinks (like citrus or soda), or even brushing your teeth too hard with a hard-bristled toothbrush.
2. Gum Recession:
When your gums recede, they expose the roots of your teeth, which are not protected by enamel. The roots contain nerve endings that can cause sensitivity when exposed to temperature changes.
3. Tooth Decay or Cavities:
Cavities or decay can weaken the enamel and cause pain. If a cavity is deep enough to expose the dentin, it can lead to increased sensitivity.
4. Cracked or Chipped Teeth:
A cracked or chipped tooth can also expose the dentin, leading to sensitivity. These cracks may also allow bacteria to enter the tooth, increasing the risk of infection.
5. Teeth Grinding (Bruxism):
Grinding or clenching your teeth can wear down enamel and lead to tooth sensitivity. This often occurs during sleep, and if left untreated, it can also cause other dental issues like cracked teeth.
6. Dental Procedures:
Recent dental work, such as fillings, crowns, or teeth whitening, can temporarily increase tooth sensitivity. While this is usually temporary, it can still cause discomfort in the days following the procedure.
Can Sensitive Teeth Be Fixed?
1. Desensitising Toothpaste:
One of the first treatments a Perth dentist may recommend for sensitive teeth is using a desensitising toothpaste. These toothpastes contain compounds that help block the nerve signals that cause pain. Over time, using desensitising toothpaste can help reduce sensitivity, especially if the cause is enamel wear or gum recession.
2. Fluoride Treatments:
A Perth dentist may apply fluoride treatments to the affected areas to help strengthen the enamel and reduce sensitivity. Fluoride can help remineralise the enamel, making it more resistant to further erosion and providing relief from discomfort.
3. Dental Sealants or Bonding:
If sensitivity is caused by worn-down enamel, your dentist may recommend dental sealants or bonding to protect the exposed dentin. This can be especially useful for patients with severe sensitivity due to enamel erosion. Sealants and bonding can help cover the sensitive areas, providing relief and preventing further damage.
4. Gum Grafting:
For those with gum recession, a gum graft can be performed to cover the exposed roots and reduce sensitivity. This procedure involves taking tissue from another part of your mouth or using synthetic material to cover the exposed roots.
5. Root Canal Therapy:
In cases where sensitivity is caused by deep tooth decay or infection, a root canal may be necessary. This procedure removes the infected pulp inside the tooth, relieving pain and preventing further infection.
6. Night Guards for Teeth Grinding:
If you grind or clench your teeth at night, your Perth dentist may recommend a custom-made night guard to protect your teeth from further damage. Night guards can help prevent enamel erosion caused by grinding, reducing sensitivity over time.
Prevention Tips for Sensitive Teeth:
While treatments can help manage sensitivity, prevention is key to maintaining a pain-free smile. Here are some helpful tips to prevent tooth sensitivity:
1. Use a Soft-Bristled Toothbrush:
Brushing your teeth too hard with a hard-bristled toothbrush can damage the enamel and lead to sensitivity. Use a soft-bristled toothbrush and brush gently in circular motions to avoid wearing down the enamel.
2. Avoid Acidic Foods and Drinks:
Foods and drinks like citrus, soda, and wine can wear down enamel over time, leading to sensitivity. Try to limit your intake of acidic foods, and rinse your mouth with water after consuming them to help protect your enamel.
3. Practice Good Oral Hygiene:
Brushing your teeth at least twice a day with fluoride toothpaste and flossing daily can help prevent enamel erosion and cavities, which are common causes of sensitivity. Make sure to brush gently along the gum line to prevent gum recession.
4. Wear a Mouthguard if You Grind Your Teeth:
If you grind or clench your teeth at night, wearing a mouthguard can help prevent damage to your teeth and reduce sensitivity caused by enamel wear. Ask your Perth dentist about custom night guards for the best fit and protection.
5. Avoid Teeth Whitening Products:
Over-the-counter teeth whitening products can sometimes cause increased sensitivity, especially if used too frequently. If you’re concerned about sensitivity, talk to your dentist before using any whitening products.
6. Stay Hydrated:
Dry mouth can contribute to tooth sensitivity, so it’s essential to stay hydrated and maintain good saliva flow. Drinking water regularly and using saliva-stimulating products can help protect your teeth from sensitivity.
