Tooth sensitivity never feels very good, and we’ve all experienced it. But do you know why it happens? Today, Accent Smile Center will answer your burning questions about what causes tooth sensitivity and how to find relief.
Causes of Tooth Sensitivity
Tooth sensitivity is also called dentin hypersensitivity. It occurs when the underneath layer of the tooth, called dentin, becomes exposed or vulnerable. This relatively common condition causes discomfort or pain in response to stimuli like hot, cold, sweet, or acidic foods and beverages. Here’s a closer look at the possible causes behind tooth sensitivity:
- Enamel Erosion: The enamel is the hard, protective layer on the outside of the tooth. It wears away due to factors like acidic foods, aggressive brushing, or other stimuli, and the dentin underneath becomes exposed. The enamel is sensitive due to the fact that it contains microscopic tubules that lead to nerve endings.
- Tooth Decay: Cavities can erode enamel and expose dentin as well, resulting in sensitivity. Decay can also cause inflammation in the tooth, increasing sensitivity.
- Gum Recession: Gum tissue recedes due to gum disease or other causes, exposing the tooth roots. Our roots lack enamel and are covered only by a thin cementum layer, making them more sensitive.
- Cracked or Chipped Teeth: A chip or crack in a tooth can likewise reveal the dentin or even reach the nerves, causing more severe pain and sensitivity.
- Brushing Technique: A hard-bristled toothbrush or brushing too aggressively also wears down enamel and causes gum recession.
- Teeth Whitening Products: Some people may not realize it prior to treatment, but some whitening products contain chemicals that can temporarily increase tooth sensitivity. Part of why we recommend doing this type of treatment professionally, as opposed to an at-home option, is so that you can better expect and manage this type of symptom.
- Dental Procedures: After dental work, like fillings, crowns, or even deep cleanings, temporary sensitivity can occur as the teeth adjust.
Treating Tooth Sensitivity
The good news is that there are a good number of ways Dr. Gatgens, Dr. Densmore, and Dr. Noble manage sensitive teeth, though prevention is always the best technique when possible. Here are some of the ways Accent Smile Center recommends helping with this discomfort:
- Use Desensitizing Toothpaste: There are several great toothpastes designed specifically for sensitive teeth. These toothpastes contain compounds that help block the pathways to nerves and reduce sensitivity over time.
- Choose a Soft-Bristled Toothbrush: Using a soft-bristled toothbrush is a good way to minimize enamel wear and irritated gums, both of which can help reduce sensitivity.
- Adopt a Gentle Brushing Technique: Regardless of what you use to brush, make sure you’re brushing with gentle pressure and in circular motions. Some people assume that brushing harder cleans better, but that’s not necessarily the case.
- Avoid Acidic Foods and Drinks: Adjusting your diet can be hard—but consumption of acidic foods and beverages, such as citrus fruits, tomatoes, and sodas, can erode enamel and elevate sensitivity.
- Rinse with Fluoride Mouthwash: Fluoride strengthens enamel and can reduce sensitivity. We always recommend using a fluoride mouthwash to provide your teeth with extra protection. You can ask our team more about how this tool helps and what some good brands are to find it in.
- Consider Professional Dental Treatments: During your cleaning, we can apply fluoride gels or desensitizing agents directly to your teeth to provide some relief.
- Address Dental Issues Promptly: If you suspect you have cavities, cracked teeth, or other dental issues, be sure to have them treated promptly. Waiting could worsen your sensitivity.
- Use a Nightguard: Tooth grinding can often happen without patients even being aware of it. If we see evidence of it, we will let you know. A custom-fitted nightguard is a great tool to help protect your teeth from this kind of damage.
FAQs About Tooth Sensitivity
Q: How does aging affect tooth sensitivity?
As we age, our enamel naturally wears down, making teeth more susceptible to sensitivity. This is part of why protecting your teeth earlier in life can make a big difference.
Q: Is there a genetic component to tooth sensitivity?
Genetics can potentially play a role in sensitive teeth. Some individuals could inherit thinner enamel or a tendency for gum recession, which can both increase the likelihood of sensitivity.
Q: Why do dental restorations, like crowns or fillings, cause sensitivity?
This is generally due to the irritation of the nerve within the tooth. It will usually stop after a little while, but contact Accent Smile Center if it continues for too long.
