Key Takeaways

Experiencing tooth pain when enjoying your favourite food and drinks can be quite disheartening. If hot or cold sensations cause pain in your mouth, you might have teeth sensitive to temperature changes or certain substances. At Thames Street Dental, we understand how much sensitive teeth can impact your daily life, and we’re here to provide expert care and effective solutions.

Understanding Tooth Sensitivity

What is Tooth Sensitivity?

Tooth sensitivity, clinically known as dentin hypersensitivity, occurs when the inner layer of your teeth, called the dentin, becomes exposed. The dentin contains tiny tubules that lead directly to the tooth’s nerve. When the tooth enamel, the outer layer of your teeth, is compromised, these tubules are no longer protected, causing pain when eating or drinking something hot, cold, sweet, or acidic. If you experience such discomfort due to sensitive teeth, it’s important to understand that treatments are available to help ease the pain and restore your oral health.

Common Symptoms of Sensitive Teeth

The primary symptom of sensitive teeth is a sharp, sudden pain or discomfort when teeth hurt due to exposure to certain triggers. These triggers often include hot, cold, sweet, or acidic food and drinks. Some people may also experience pain when brushing their teeth or even when exposed to cold air. This tooth sensitivity can be temporary, but it can also be a chronic problem, indicating underlying dental issues that require attention from your dentist. Recognising these symptoms early is crucial for seeking timely dental care.

How Sensitive Teeth Affect Oral Health

Sensitive teeth can cause significant changes in your oral health habits. The pain of sensitive teeth may cause you to avoid brushing sensitive areas thoroughly, potentially leading to tooth decay and gum disease. Additionally, discomfort might make you change your diet, avoiding nutritious but potentially triggering food and drinks. Maintaining good oral health is essential, and addressing tooth sensitivity promptly can prevent further complications. Your dentist and dental team are here to help you manage this condition effectively.

Possible Causes of Sensitive Teeth

Enamel Erosion and its Impact

One of the major possible causes of sensitive teeth is enamel erosion. The tooth enamel serves as the protective outer layer of your teeth, shielding the dentin. Acidic food and drinks, such as citrus fruits and fizzy drinks (or sodas for our American friends), can gradually wear away the tooth enamel. Similarly, certain medical conditions that increase stomach acid can also erode enamel. When the enamel thins, the dentin becomes exposed, which can cause sensitivity. Using fluoride toothpaste and limiting acidic food and drinks can help protect your tooth enamel and prevent tooth sensitivity. Regular dental care and check-ups with your dentist are essential to monitor and maintain the health of your tooth enamel.

Gum Recession and Exposed Roots

Gum recession is another factor that causes sensitivity. When the gums pull away from your teeth, the roots of your teeth become exposed. The tooth root lacks the protection of tooth enamel, making it more susceptible to hot or cold temperatures and acidic substances. Brushing too hard or having gum disease can lead to gum recession. Addressing gum disease early and using a soft-bristled brush can help prevent further gum recession. If you notice your gums receding, ask your dentist about treatment options to protect the exposed roots and treat sensitive teeth.

Cavities and Tooth Decay

Cavities and tooth decay are also possible causes of sensitive teeth. When decay erodes the tooth enamel and reaches the dentin, it can cause sensitivity and tooth pain. Bacteria in the mouth produce acids that attack the tooth enamel, leading to cavity formation. Regular brushing and flossing can help prevent tooth decay. Fluoride toothpaste strengthens the tooth enamel, making it more resistant to acids. If you experience tooth sensitivity, it is important to visit your dentist to address any cavities or areas of decay promptly. Early treatment can prevent further damage and help ease the pain.

Treatments for Sensitive Teeth

Over-the-Counter Solutions

Several over-the-counter products can help treat sensitive teeth. Desensitising toothpaste, containing compounds like potassium nitrate or stannous fluoride, can help desensitise the nerves in the teeth and reduce tooth sensitivity. It may take several weeks of regular use to notice a significant improvement. Soft-bristled toothbrushes are also recommended to avoid further irritating gums and enamel. Additionally, fluoride mouth rinses can strengthen the tooth enamel and provide extra protection against sensitivity. If over-the-counter solutions do not provide sufficient relief, ask your dentist about other treatment options.

Professional Dental Treatments

When over-the-counter treatments are not enough, several professional dental procedures can effectively treat sensitive teeth. Fluoride varnish applications, performed by your dental team, can strengthen the tooth enamel and reduce tooth sensitivity. Dental bonding involves applying a tooth-colored resin to cover exposed tooth roots or areas of enamel loss. In severe cases, a root canal may be necessary to remove the affected nerve and relieve tooth pain. Your dentist can determine the most appropriate treatment based on the cause and severity of your tooth sensitivity.

Home Remedies for Sensitive Teeth

In addition to professional and over-the-counter options, several home remedies can help manage sensitive teeth. Rinsing your mouth with warm salt water can help reduce inflammation and soothe sensitive areas. Avoiding acidic food and drinks can prevent further enamel erosion. Using a straw when drinking acidic beverages can minimise contact with your teeth. Additionally, some people find relief by applying clove oil to sensitive teeth. While home remedies can provide temporary relief, it is essential to consult with your dentist for a comprehensive evaluation and treatment plan.

Dental Care for Sensitive Teeth

Choosing the Right Toothpaste

Selecting the right toothpaste is crucial in managing sensitive teeth and promoting good oral health. Look for a desensitising toothpaste containing fluoride, which helps strengthen the tooth enamel and protect against tooth sensitivity. These toothpastes often include ingredients like potassium nitrate that help desensitise the nerve endings in the dentin, reducing pain. When choosing, ensure the toothpaste is suitable for sensitive teeth, effectively helping to treat sensitive teeth and maintain dental care.

Proper Brushing Techniques

Proper brushing techniques can significantly impact tooth sensitivity. Always use a soft-bristled brush to avoid irritating the gums and wearing down the tooth enamel. Gently brush your teeth in circular motions, ensuring you clean all surfaces, including the gum line. Brushing too hard can cause gum recession and further expose the dentin, making your teeth sensitive. It is crucial to brush your teeth at least twice a day to maintain optimal oral health and prevent different causes of tooth sensitivity.

Regular Visits to the Dentist

Regular dental visits are essential for managing and preventing sensitive teeth. Your dentist can identify the possible causes of your tooth sensitivity, such as enamel erosion, gum recession, or cavities. They can also provide professional treatments like fluoride varnish or dental bonding to protect sensitive areas. During these visits, your dental team can offer personalized advice on oral health care and recommend the most suitable products for sensitive teeth, which can help ease the pain.

These signs may indicate serious underlying problems that require immediate treatment. Ignoring these can lead to tooth decay, gum disease, or more severe complications. Your dentist may provide treatment options to treat sensitive teeth.

Questions to Ask Your Dentist

During your dental appointment, it’s important to ask your dentist about your sensitive teeth. Inquire about the specific cause of your tooth sensitivity and ask for recommendations on managing and treating it effectively. Discuss the best type of desensitising toothpaste, proper brushing techniques, and whether professional dental procedures like fluoride applications or dental bonding are necessary. Ask your dentist about preventive measures to protect your tooth enamel and prevent further sensitivity. Your dentist may also know different causes of sensitive teeth.

Preventive Measures for Oral Health

Taking preventive measures is crucial for maintaining good oral health and preventing sensitive teeth. Ensure you brush your teeth at least twice a day with a fluoride toothpaste and use a soft-bristled brush to avoid gum recession. Limit your consumption of acidic food and drinks that can erode tooth enamel. Consider using a fluoride mouthwash to strengthen your tooth enamel. Also, ask your dentist for up-to-date advice on caring for teeth and gums, and guide patients toward the best treatment suited to their individual health needs.
