Having your teeth professionally cleaned should leave you with a brighter, healthier smile. However, some people experience lingering sensitivity for weeks afterward. This isn't uncommon, but it's important to understand why it happens and what you can do to alleviate the discomfort. This article explores the causes of post-cleaning teeth sensitivity, offers effective solutions, and answers frequently asked questions.
Why Are My Teeth Sensitive After a Cleaning?
The most common culprit is exposed dentin. During a professional cleaning, the hygienist uses tools to remove plaque and tartar buildup, sometimes inadvertently scraping away some enamel. This exposes the dentin, the layer beneath the enamel, which contains microscopic tubules leading to the tooth's nerve. When these tubules are exposed, they become sensitive to hot, cold, sweet, or acidic substances.
Other potential causes include:
- Aggressive cleaning: While thorough cleaning is vital, overly aggressive techniques can also lead to enamel erosion and sensitivity.
- Gum recession: Gum recession exposes the roots of your teeth, making them more susceptible to sensitivity. This can be caused by various factors, including gum disease (gingivitis or periodontitis) and aggressive brushing.
- Recent dental work: Sensitivity can persist for several weeks after procedures like fillings, crowns, or whitening treatments.
- Underlying dental issues: In some cases, persistent sensitivity might indicate a more significant problem, like a cavity, cracked tooth, or nerve inflammation.
How Long Does Post-Cleaning Sensitivity Usually Last?
For most people, post-cleaning sensitivity subsides within a few days to a week. However, if it lasts for several weeks, it warrants a follow-up visit with your dentist. Prolonged sensitivity could signal an underlying issue requiring attention.
What Can I Do to Relieve the Sensitivity?
Several strategies can help manage sensitivity after a professional cleaning:
- Use a desensitizing toothpaste: These toothpastes contain ingredients like potassium nitrate or strontium chloride that block the nerve signals responsible for sensitivity. Look for toothpastes specifically labeled as "desensitizing" or "for sensitive teeth."
- Avoid irritating foods and drinks: Temporarily abstain from consuming excessively hot, cold, sweet, or acidic foods and beverages. This minimizes direct stimulation of the exposed dentin.
- Gentle brushing: Use a soft-bristled toothbrush and brush gently with short, circular motions. Avoid aggressive scrubbing, which can further irritate your gums and enamel.
- Proper flossing technique: Floss gently to avoid damaging your gums.
- Rinse with fluoride mouthwash: Fluoride strengthens enamel and can help reduce sensitivity over time.
- Over-the-counter pain relievers: For temporary pain relief, you can consider taking acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) as directed on the label.
Is Post-Cleaning Sensitivity Normal?
Yes, some degree of post-cleaning sensitivity is considered normal, especially immediately after a cleaning. However, the intensity and duration should be relatively short-lived. Persistent or severe sensitivity indicates the need for professional assessment.
When Should I See My Dentist About Sensitive Teeth?
If your sensitivity persists for more than a week or two, intensifies, or is accompanied by other symptoms like pain, swelling, or bleeding gums, schedule an appointment with your dentist immediately. This is especially crucial if the sensitivity is severe enough to interfere with your ability to eat or drink comfortably. They can properly diagnose the cause and recommend appropriate treatment.
Can My Dentist Do Anything to Help?
Your dentist can assess the cause of your sensitivity and recommend the most appropriate course of action. They might suggest further treatments, such as applying fluoride varnish or sealants to protect exposed dentin and reduce sensitivity. In some cases, more extensive treatment might be necessary to address underlying issues like gum disease or cavities.
