Can Stress Affect Your Teeth and Gums?
Yes, mostly in indirect ways. Stress often shows up as clenching or grinding, it makes it harder to keep up with brushing and regular visits, and the National Institute of Dental and Craniofacial Research lists stress among the factors associated with gum disease. Many medicines for anxiety and depression also cause dry mouth, which raises the risk of cavities. Each of these can be managed once it's recognized.
How can stress affect your gums?
Stress is associated with gum disease, along with smoking, some illnesses and their medications, and hormonal changes. Part of the link is practical. When life is hard, people brush less carefully, skip cleanings, smoke more or snack more often. Stress may also affect how the body handles inflammation, which is one reason gum problems can be harder to control during difficult stretches.
If your gums bleed when you brush or feel puffy or tender, that's worth checking whatever the cause.
Why do anxiety and depression medicines cause dry mouth?
Hundreds of medicines can reduce saliva, including many antidepressants and anti-anxiety medicines. Saliva rinses away food, buffers acid and helps repair early enamel damage. With less of it, cavities can form faster, especially along the gumline and around old fillings.
If your mouth feels dry:
Keep taking your medicine as prescribed, and tell your prescriber about the dry mouth. Sometimes a change is possible, and sometimes it isn't.
Tell us about every medication you take, including recent changes.
Sip water through the day, and chew sugar-free gum to help saliva flow.
Cut back on sugary drinks and frequent snacks.
For patients with medication-related dry mouth, we talk through fluoride products for home use, saliva aids and how often to come in so problems are found while they're small. Our page on dry mouth explains causes and options in more detail.
How does stress lead to tooth grinding?
Many people clench or grind when they're under pressure, during the day while concentrating or at night in their sleep. Over time this can:
Wear teeth down, shortening them and changing how they meet
Break fillings and crowns or crack teeth
Strain the jaw muscles and joints, leading to soreness and headaches
A custom-fitted night guard can protect teeth and dental work from those forces. It usually won't stop the clenching itself, so it helps to notice daytime habits too. Read more about tooth grinding and bruxism.
What if the dental visit itself makes you anxious?
That's common, and it's worth telling us. New-patient visits at our office are scheduled for two hours, normally an hour with me and an hour in hygiene. That time lets us go through your history and medications, talk about what worries you, and plan care at a pace that works for you. I've written about how I approach dental anxiety. Patients with complicated health histories can read about our approach to medically involved care.
