Plenty of patients tell us their mouth feels dry and they assume it is just part of getting older or not drinking enough. Sometimes that is true. Often, though, there is a clear reason, and once we find it the relief options are better than they have ever been. A dry mouth, known medically as xerostomia, deserves attention because saliva does a lot of quiet work to protect your teeth, and when it runs low, problems follow.
What is actually causing it
Saliva production drops for a handful of common reasons, and knowing which one applies to you points to the right fix.
Medications are the biggest culprit. Hundreds of everyday prescriptions list dry mouth as a side effect, including treatments for high blood pressure, allergies, anxiety, depression and chronic pain. If you take more than one, the effect adds up. This is worth mentioning to us, because we can plan around it.
Age plays a role, partly because older adults take more medication and partly because saliva glands can become less productive over time. Mouth breathing, often at night or due to a stuffy nose, dries things out, as does simple dehydration after exercise or a hot day. Certain health conditions and some cancer treatments also reduce saliva.
Why a dry mouth is hard on your teeth
Saliva is not just water. It rinses away food, neutralises the acids that erode enamel, and delivers minerals that help repair early damage to the tooth surface. Take that protection away and the mouth becomes a friendlier place for decay. People with a lasting dry mouth tend to get cavities faster, sometimes in spots that rarely decay otherwise, near the gumline and between the teeth. Gums get more easily irritated, bad breath becomes more stubborn, and fungal infections like thrush turn up more often. Dentures and aligners also feel less comfortable without that natural lubrication.
The remedies worth trying now
The good news is that managing dry mouth has come a long way. The current approach layers a few simple habits with products designed specifically for the problem.
Start with hydration and habits
Sip water through the day rather than gulping it occasionally, and keep a bottle within reach at your desk or bedside. Cut back on caffeine and alcohol, both of which dry the mouth, and skip alcohol-based mouthwashes, which make things worse despite the fresh feeling. A humidifier in the bedroom helps if you breathe through your mouth overnight.
Saliva substitutes and stimulants
Over-the-counter saliva substitutes have improved a great deal. The newer moisturising gels and sprays coat the mouth and last noticeably longer than older versions, which is a relief overnight. To gently encourage your own saliva, sugar-free gum and lozenges containing xylitol are a reliable choice, and xylitol has the bonus of discouraging cavity-causing bacteria.
Products built for dry mouths
There are now full ranges of toothpastes, rinses and gels formulated for dry mouths, many using enzymes that mimic saliva's protective role. We often pair these with a higher-fluoride toothpaste or in-office fluoride treatments to give thirsty enamel extra defence. The right combination depends on the cause and severity, which is exactly what we sort out at a visit.
When to bring it to us
If your mouth feels dry most days, if a new medication made it worse, or if you have noticed fresh sensitivity or cavities, book a visit. At your appointment we look for early damage, recommend products suited to you, apply protective fluoride and, importantly, set a cleaning and check-up schedule that keeps ahead of decay. If a cavity has already formed, our dental fillings restore the tooth gently before it grows into something bigger. Because dry mouth affects people of every age, our family dentistry team can look after the whole household in one place on the Mountain.
