The Impact of Dry Mouth on Your Teeth and Gums

Dry mouth might seem like a small annoyance—until it starts affecting your teeth, gums, and comfort day to day. If your mouth often feels sticky, you wake up thirsty, or you’re constantly reaching for water, it may be more than dehydration.
Saliva does a lot more than keep your mouth comfortable. It helps remove food particles, balances acids, and supports enamel by providing the minerals your teeth need.

When saliva flow drops, your mouth loses some of its natural protection—meaning bacteria and acids can do more damage, more quickly.

Why Dry Mouth Happens

Dry mouth can be caused by many everyday factors, including:

• Certain medications (including allergy meds, antidepressants, and blood pressure medications)
• Mouth breathing (especially during sleep)
• Stress (which can affect saliva production more than people realise)
• Caffeine or alcohol intake
• Not drinking enough water
• Some health conditions

How It Can Affect Oral Health

When your mouth is consistently dry, you may notice:

• Bad breath that doesn’t improve with brushing
• More plaque buildup
• Increased tooth sensitivity
• Higher risk of decay, especially near the gumline
• Gum irritation or inflammation
• Sore spots, burning sensations, or cracked lips

Dry mouth can also make it harder to wear certain dental appliances comfortably, and it may affect eating and speaking—especially if the dryness is noticeable throughout the day.

Simple Ways to Support a Healthier Mouth

The good news is that small changes can make a big difference:

• Sip water regularly (especially after coffee)
• Chew sugar-free gum to stimulate saliva
• Try a humidifier at night if you mouth-breathe
• Limit alcohol-based mouthwashes, which can be drying
• Avoid frequent sugary snacks

If you notice dry mouth often, it’s worth mentioning at your next check-up. Sometimes it’s a simple habit shift. Other times, it helps to look at medications, sleep habits, or recommend products that support moisture and comfort.
