Have you ever passed on ice cream because you know it will hurt your teeth? What about a hot cup of coffee? If yes, you might have sensitive teeth. Besides being uncomfortable, tooth sensitivity might be a sign of a deeper problem. It might mean a dental emergency is close. Seeing your dentist about sensitivity is the best way to prevent emergencies. Read on to learn about why your teeth are so sensitive.
What Causes Sensitive Teeth?
When the outermost part of the tooth, called enamel, wears down, it exposes microscopic tubes in the layer of tooth below, called the dentin. Sensitivity is caused by the cells within these tubes being stimulated. This can be caused by extreme temperatures through food, beverages, and even the air.
Enamel can be worn down by several things, including:
- Tooth grinding
- Receding gums due to age
- A diet high in acidic beverages
- Aggressive brushing
Cracks in the enamel can also result in sensitivity. Severe hot and cold can cause the teeth to expand and contract. Over time, microscopic cracks can develop, allowing hot or cold sensations to enter the nerves beneath the enamel.
Do Sensitive Teeth Mean I Have a Dental Emergency?
Having sensitive teeth, especially in the short term, does not necessarily constitute an emergency. However, if the sensitivity has persisted for longer than a couple of days, it could be a sign of a cavity or an infected tooth pulp.
When in doubt, contact your emergency dentist. Sometimes all you need to alleviate the pain is a prescription of desensitizing toothpaste or a protective coating over the teeth. However, if the pain is severe and cannot be relieved by these methods, your dentist may suggest root canal therapy. In a root canal, the infected pulp is removed, relieving pain.
How Can Sensitive Teeth Be Treated?
If your discomfort is mild or sporadic, there are a few things you can do to relieve the pain, such as:
- Change your toothpaste. Some toothpastes, especially ones with whitening agents, can increase sensitivity. Try a toothpaste specifically designed to treat sensitive teeth. You can find these kinds of toothpaste at most drug stores. It’s important to note that many of these treatments must be used regularly for at least a month before you start feeling results. For quicker relief, try massaging the toothpaste onto your gums with your finger after brushing with it.
- Be gentle with your teeth. Don’t use hard-bristled brushes or brush too vigorously, as it can further wear down the enamel and cause more pain. Use a soft-bristled brush for less pressure. Brush at a 45-degree angle so you don’t damage your gums.
- Avoid acidic foods. Certain foods can irritate sensitive teeth, including those with a high acidic content. These include sodas, coffee, fruit juices, wine, and many popular energy drinks.
Tooth sensitivity is a common problem. However, that doesn’t mean that it should be ignored. It could be a symptom of a larger issue. If you would like to stop the discomfort and learn what is causing it, contact your emergency dentist today!
