Age-related Causes of Tooth Sensitivity

Posted on December 5, 2024 in Healthy You

Although young people can experience tooth sensitivity, it’s a common complaint among seniors. This sharp, shooting sensation can make enjoying your favorite foods and beverages uncomfortable and even painful. Here, we explain some of the age-related reasons why teeth become more sensitive and what you can do to ease it.

The link between age and tooth sensitivity
Overall, tooth sensitivity is caused by an issue with your enamel — the white outer coating of your tooth. The enamel covers and protects the dentin of your tooth. If your enamel wears away, the dentin is exposed and extreme temperatures — cold or hot — are quickly transmitted to the nerve at the center of the tooth. This causes the nerves to react and can result in pain.

One of the most common age-related causes of tooth sensitivity is wear and tear, which simply means that your enamel thins over time. Years of rough toothbrushing, lack of good oral hygiene, consuming highly acidic foods (like tomatoes and citrus) and teeth grinding can all lead to the wearing down of enamel, leading to tooth sensitivity.

Another age-related cause of tooth sensitivity is gum disease and receding gums (when the gums pull away from your teeth), which become more common as we get older.

Dry mouth may also lead to tooth sensitivity in older adults. Dry mouth is a common issue for seniors, often caused by medications or medical conditions. Saliva plays an important role in keeping your mouth healthy by washing away food particles and buffering harmful acids. When saliva production decreases, your teeth are more prone to cavities and sensitivity.

Simple ways to ease tooth sensitivity at home
The harsh reality with enamel is that once you lose it, you can’t grow or get it back. That’s why it’s important to address any concerns about tooth sensitivity as early as possible. Many forms of tooth sensitivity are mild and can be managed at home. Here are some ways you can help protect your enamel and reduce tooth sensitivity:

• Update your at-home dental products: Using a desensitizing toothpaste and fluoridated mouthwash may help reduce tooth sensitivity. We always suggest a soft-bristled toothbrush but if you experience sensitivity, you may want an extra soft toothbrush to allow for more gentle brushing. 
• Make a few dietary changes: Limiting acidic food and drink (like citrus, tomatoes, tea and soda) in your diet can reduce enamel erosion, and avoiding ultra hot or icy items can help lessen tooth sensitivity symptoms.
• Practice good oral hygiene: Brushing twice a day and flossing regularly keeps your teeth and gums healthy.
• Drink plenty of water: Staying hydrated is a great way to prevent dry mouth.

When to see your dentist for tooth sensitivity
If at-home options aren’t helping your tooth sensitivity, it’s important to see your dentist. Sensitivity could be a sign of a bigger problem like cavities or gum disease. Your dentist can find the cause of your sensitivity and recommend dental procedures to protect your teeth and reduce sensitivity.

You don’t have to live with tooth pain
Some increase in tooth sensitivity is normal as we age, but it doesn’t mean you have to live in discomfort. By understanding the causes of sensitivity and working with your dentist, you can keep your teeth healthy and reduce pain, allowing you to continue enjoying your favorite foods and drinks.
