Tooth Sensitivity: Causes, Treatments, and Dental Anxiety - Dentistry

More Info

---

Tooth sensitivity is a common dental issue that can arise from various factors, including gum recession, enamel wear, and dental procedures. It can lead to discomfort when consuming hot, cold, or sweet foods, and may also cause pain during brushing or flossing. In your case, the bleeding when using dental floss and the sensitivity in your canine teeth suggest that there may be underlying gum issues or enamel erosion.


Causes of Tooth Sensitivity
1. Gum Recession: When gums recede, the roots of the teeth become exposed. This area is not covered by enamel and is more sensitive to temperature changes and pressure. The bleeding you experience while flossing may indicate gum inflammation or periodontal disease, which can exacerbate sensitivity.

2. Enamel Erosion: Enamel can wear away due to aggressive brushing, acidic foods, or beverages, leading to increased sensitivity. If the enamel is compromised, the underlying dentin becomes exposed, which contains tiny tubules that lead to the nerve endings in the tooth.

3. Dental Procedures: Recent dental work, such as fillings or cleanings, can temporarily increase sensitivity. This is often due to the manipulation of the tooth structure or the use of dental tools that may irritate the nerves.

4. Brushing Technique: Brushing too hard or using a hard-bristled toothbrush can damage the gums and enamel, leading to sensitivity and bleeding.


Treatment Options
1. Desensitizing Toothpaste: These toothpastes contain compounds that help block the transmission of sensation from the tooth surface to the nerve. Regular use can significantly reduce sensitivity over time.

2. Fluoride Treatments: Professional fluoride treatments can strengthen enamel and reduce sensitivity. Your dentist may apply a fluoride varnish or gel to your teeth during a visit.

3. Gum Treatment: If gum disease is present, your dentist may recommend a deep cleaning (scaling and root planing) to remove plaque and tartar buildup, which can help reduce inflammation and bleeding.

4. Dental Sealants: These can be applied to the chewing surfaces of teeth to protect them from decay and sensitivity.

5. Root Canal Treatment: In severe cases where sensitivity is due to nerve damage or infection, a root canal may be necessary to remove the affected nerve tissue.


Managing Dental Anxiety
It's understandable to feel anxious about dental visits, especially if you have had uncomfortable experiences in the past. Many dental offices now offer sedation dentistry options, including:
1. Local Anesthesia: This numbs the area being treated, so you won’t feel pain during procedures. It is commonly used for fillings and cleanings.

2. Nitrous Oxide (Laughing Gas): This is inhaled through a mask and helps you relax during the procedure. It wears off quickly, allowing you to drive yourself home afterward.

3. Oral Sedation: This involves taking a sedative pill before your appointment, which can help you feel calm and relaxed.

4. IV Sedation: For more extensive procedures or for those with severe anxiety, sedation can be administered through an IV, allowing for deeper relaxation.


Conclusion
Given your symptoms of sensitivity and bleeding, it is essential to schedule a follow-up appointment with your dentist. They can assess your gum health, recommend appropriate treatments, and discuss sedation options to make your visits more comfortable. Remember, maintaining good oral hygiene practices at home, such as gentle brushing with a soft-bristled toothbrush and regular flossing, is crucial for preventing further issues. Don't hesitate to communicate your fears and concerns with your dental provider; they are there to help you feel at ease and ensure your dental health.
