There is no denying that stress can cause a whole host of other issues. It can result in a lack of sleep, it can have a bad influence on your social life, and it can cause you to gain weight. But, did you know that it could also cause problems with your mouth, gums, and teeth too? While you are working on your stress levels, read on to find out about the different ways stress manifests in the mouth and what you can do to minimize the impact.

Teeth grinding – A lot of people grind and clench their teeth when they are feeling stress. This can happen during the day, as well as while you are sleeping. Some people grind their teeth without even realizing they are doing it. Once you start to grind your teeth, you can end up in a vicious cycle of doing it more and more, which can cause problems with your TMJ joint. If you think the issue has already got out of hand, it is best to see a professional, such as those at http://www.bcdentalhealth.com/. They may recommend that you use a night guard while you are asleep to prevent you from grinding your teeth. What about during the day? Practice keeping your teeth slightly apart when you are not eating.

Cold sores – Herpes simplex virus is the cause of cold sores, which are also known as fever blisters. They often show up around your lips or on them, and they are filled with fluid. Sometimes people also get cold sores on their chin or under their nose. An outbreak can easily trigger if you are feeling upset, which is why stress management is so important. Check out these stress relief tips for some assistance: https://stressreliefformothers.com/stress-relief-for-mothers. If you do suffer a breakout, cold sores do tend to heal on their own within roughly a week. You can also get medication over the counter to help you.

Mouth sores – You may also get sores inside of your mouth. These are known as canker sores, which are little spots with a grey or white base and red borders. To make matters worse, these sores don’t always turn up on their own, they can appear in pairs and sometimes in even bigger numbers. Don’t make matters worse by eating foods that have a high acid content and try to avoid anything that is hot or spicy. If you do this, your canker sore should disappear within around a week. If you are in pain, get some numbing medicine from your nearest pharmacy. Of course, if matters get worse or persist for longer than ten days, see a dentist.

Hopefully, you now feel more prepared for looking after your mouth, teeth, and gums while also managing your stress levels. There is no denying that stress has a funny way of showing itself, and the last thing you want to do is feel even worse because of sores in your mouth!


You probably thought the last place stress could attack you was your mouth, well you were wrong. Just like other physical issues, these dental problems can get worse if you don’t get them under control. 

Teeth grinding can cause you to wear your teeth down over time but since you may not be aware you are doing this, it is important to talk to your dentist if you suspect you are. A clue you may be grinding your teeth at night is a sore jaw in the morning.

Reducing the urge is one of the best ways to keep you from grinding your teeth, this can be achieved a few ways. Although most teeth grinding happens during sleep, it is important that you get your rest, when you are properly rested you are less likely stressed. 

Staying hydrated is another way to help lower the urge to grind your teeth at night. This is because the fluids will help make the tissues in the jaw swell up making a cushion for the bones and teeth in your mouth. 

Lastly, eat a diet full of foods that can help reduce stress, get enough exercise, and take time to yourself every day this way you can keep your stress levels down and reduce the chance of dental problems. 

Have you experienced any of these dental issues and you suspect they were caused by stress?

  1. Your comment about staying hydrated hit home with me. Many times when I sleep I can tell when I haven’t drunk enough fluids or I had a lot of carbs and my mouth is dry all night. These are also the nights that my wife wakes me up more often and tells me to stop snoring.

    I use to grind my teeth a lot also but that doesn’t seem to be much of an issue these days. Thank you for bringing this up because stress is a big problem any many peoples lives and I believe was a major factor in me having a stroke.

    1. Hi Rick,
      I am glad that you found the information useful. I think we all can use a reminder now and then to take care of ourselves. Stress can be a big problem in many of our lives and it can sadly lead to strokes so it is important to reduce as much of it as you can. Thanks for your comment!

  2. This is a very interesting article, I never knew that stress could cause you problems in your mouth. I guess it makes sense with the teeth grinding I often find myself doing this when stressed out. Offering diet solutions is always nice too since I’m very food conscience of what I feed my body.

    1. Hi Alex,
      That is interesting! I grind my teeth when my seizures are out of control which I guess you can say are stress related so it is crazy what stress can do. But yes a healthy diet is always one of the best solutions to a healthy lifestyle.

  3. I never knew stress could affect my mouth. When I saw the title of your article, I was just wondering how is that even possible. At least I learned something I never ever thought of before. And some recommendations in case stress ever gets the better of me

    1. Hi Aladin,
      Don’t worry you are not the only one not aware of what stress can do to your mouth. Stress can affect our body in many different ways so it is important to reduce it as much as possible. I am glad you found the article useful and thanks for the comment!

  4. Stress does affect us all in different ways and cold sores are one way this manifests with me when I am stressed and run down. Horrible things!
    I do believe staying hydrated will help and thanks for the reminder.
    I might try drinking a glass of water before bed and do you think this might help my snoring?
    My wife would be very happy to get some good news there 🙂
    Thanks again for a good article

    1. Hi Colin,
      Yes, you are right, stress does affect us in different ways and unfortunately, some of us have to deal with cold sores or dry mouth. Some ways to ease snoring at night include:
      Sleeping on your side – you can use a body pillow to help make this easier
      Practicing good sleep hygiene – like going to sleep the same time at night
      Changing your pillows- because it could have allergens like dust mites that could accumulate in your pillow causing you to snore
      Staying well hydrated – when you are dehydrated your nasal passage can become stickier
      Opening your nasal passages – use breathe right strips to help open your airway

      So yes, drinking more water is one of the ways you can help yourself snore less. Even taking a shower before bed is helpful. Try different things and see what may help. Hope this helps!

  5. Hey Melissa, a few members of our family including my wife occasionally suffers from cold sores, they painfully appear around the lips and nose, always after stressful situations.
    At first, our thoughts concerned the symptoms of a fluey type of cold virus was emerging but it happens every time there’s pressure related issues at work or around family matters. For instance, lately my mother-in-law’s been admitted into a nursing home, a stressful time for every family member yet sure enough cold sores keep appearing around the same areas you’ve mentioned and causing issues this last 6 months. We agree with you, it’s simply down to stress we feel,

    1. Hi Simon,
      I am sorry to hear about the stressful issues you and your family are having to face but yes it does seem like it is stress-related cold sores. I am an epileptic and although my seizures are under control now I did notice a spike in a seizure when I faced stressful issues like family illnesses. The best thing your family can do is try to reduce some of their stress during these stressful times. Maybe they can try meditation? They should definitely add some foods that reduce stress to their diet. I wish you and your family all the best, thanks for the comment!

  6. I had no idea that stress could cause Canker sores or Cold sores, so thank you for teaching me that today! I am definitely guilty of being a stress clencher though. Thankfully I don’t grind my teeth, but I often will catch myself clenching my jaw if I’m stressed or anxious about something. I’m working to break the habit, but as you mentioned, it can be hard because often times you don’t even realize you’re doing it!

    Thanks for the informative post! I’ll now have to watch out for canker sores and cold sores as well.

    1. Hi Brittaney,
      I am glad you learned something new, you know what they say knowledge is power. Clenching your jaw can be tied to stress and anxiety, if you do this habitually it will be hard and you will need to do more than stop. Have you tried yoga or meditation to relieve some of your stress and anxiety? Try to keep your stress levels in check and read those great novels you like before bed. Hopefully, that will help too! Thanks for the comment.
