Keep Your Teeth: Simple Habits for Post-40 Dental Health

15. Get Screened for Sleep Apnea

Sleep apnea doesn’t just affect your breathing—it can damage your teeth. Many people with untreated sleep apnea grind their teeth during sleep, unknowingly wearing down enamel and increasing the risk of fractures and eventual tooth loss. If you wake up with jaw pain, headaches, or feel exhausted despite a full night's rest, it might be time to get screened. Treating sleep apnea can reduce bruxism and protect your teeth from chronic nighttime stress. It’s a surprising connection—but one that highlights how oral health and systemic health are more closely linked than we think.

16. Replace Your Toothbrush on Time

An old, frayed toothbrush isn’t just ineffective—it can actually harm your teeth and gums. Over time, worn bristles lose their cleaning power and may become too abrasive, leading to gum recession or enamel wear. Replace your toothbrush (or electric brush head) every 3–4 months, or sooner if the bristles are splayed. Mark it on your calendar, or tie it to the change of seasons. This simple switch ensures you’re brushing effectively without doing damage—a small maintenance habit that supports the long game of keeping your teeth intact and your mouth healthy.
