Hi, Dr. Mark Burhenne here of AsktheDentist.com A lot of my patients ask me, “Why is my mouth so dry and what should I do about it?” If you don’t do anything about a dry mouth, the consequences are huge. For example, the number one cause for cavities, it’s not diet, it’s not biofilm management, which is brushing and flossing, and it’s not genetics. It is a dry mouth. So, I hope that piques your interest in dry mouth and you should be asking yourself, “Why is my mouth so dry?”, if it is. And so, here are the reasons you don’t want a dry mouth? It can change your whole flora, your population of bugs in your mouth to a point where your teeth cannot fix themselves. They cannot remineralize or fix themselves as they’re getting cavities. You may get bad breath. You may get gum disease. I mean, it changes everything in the mouth. So, dry mouth is very important to recognize. The causes of dry mouth are typically mouth breathing, of course. So, if you can’t breathe your nose at night or even during the day, that will dry out your mouth. Certain medications, actually most medications will cause dry mouth. So be aware of, you know, the fact that that can happen if you’re taking medication. And the other reason is you have allergies. You can’t breathe through your nose because you’re stuffed up. Something is preventing you from breathing through your nose. So, what can you do about it? Well, I’ve referred to the medication thing. You have to go back to your doctor and try and get off the medication, if you can. Find out the root cause. Fix it that way or change the medication so it doesn’t have that effect on your nose, your ability to nose breathe. The other thing, the big one for me is mouth taping. A lot of people should try mouth taping. If you have a dry mouth in the morning, tape your mouth shut at night and that will fix the problem, if the tape can stay on. Now, if the tape can’t stay on, at least you’ve tried taping. And that tells you, differentially, it tells you that you can’t breathe through your nose. You need to see an ear, nose and throat MD. They need to send a little camera down your nose and find out why you can’t breathe through your nose. So anyway, mouth breathing is a big deal. Again, I think it’s the number one reason for cavities in children and in adults. And you should be asking that question, too. “Why is my mouth so dry?” I hope those tips help and if you have any comments, please let me know in the comments below. I look forward to seeing you in the next video

  1. Hi dr. B. This is an interesting topic for me since I do get very dry mouth, but mostly during the night. It happens practically every night and I can feel it starting to happen just as it gets closer to my bedtime. I don't have any extreme breathing difficulties nor allergies nor do I take any medication. Imbibing some extra glasses of water before hitting the bed does not help, either. Food isn't an issue neither since I typically don't eat anything several hours before going to bed.

    I have mentioned this to my doctor(s) on several occasions, but any useful advice is still forthcoming. This has only been going on for the last 5 years or so and I've mostly grown used to it, but it's still quite bothersome.

  2. Gone through years without sleeping with mouth open, then years with. There are other reasons and ways to truly solve this without an ear nose throat doctor

  3. Hi Dr. B,

    I would like to point out that while an ENT can be critical to restoring nasal breathing, dentists have a unique role with their capacity to deliver appliances that expand the maxilla and remodel the upper airway. Dr. David G. Singhs DNA/Vivos appliance, and Dr. Ted Belfors Homeoblock achieve this even in adults. I think you would find Dr. Mark A. Cruz's Airway Mini-Residency really quite fascinating, though I suppose with you being next-door to Stanford you may already be aware of much of the information covered. Still, I can't recommend attending the program enough to medical professionals.
