Why Students Grind Their Teeth and How to Stop

Bruxism, commonly known as tooth grinding, isn't just a problem for young children and older adults — it can happen to people of any age, including university students. If you've started getting pain or sensitivity in your jaw, your teeth look flattened or you're having trouble sleeping, grinding could be the cause.


Thankfully, you can find easy solutions to bruxism. Here are three reasons why students might grind their teeth along with how to fix the problem.


1. Pulling All-Nighters

If you're like most students, you probably start the academic year with plans to keep on top of all your work, only to find yourself falling behind on deadlines weeks later. When due dates and exams are fast approaching, the only way to get all your assignments and studying done on time is to stay up all night working.


All-nighters are a common feature of university life, but they can wreak havoc on your dental health if you use caffeine to stay awake. Unfortunately, this stimulant doesn't only affect you when you're awake. After you write your essays, review your notes and finally get the chance to catch some sleep, the caffeine you've drunk will carry on working. This can lead to an elevated heart rate and excess muscle activity in your sleep, which triggers tooth grinding.


If caffeine is the cause of your bruxism, you'll probably notice that your mouth and jaw are sore the day after staying up all night to study. The only way to reduce caffeine-induced tooth grinding is to reduce your caffeine intake altogether.


Instead of pulling all-nighters to get your work done, try your best to keep on top of all your deadlines. If you do have to stay up late to study, opt for less harmful ways to keeping yourself awake: exercise during your breaks, eat energy-boosting snacks or play some high-tempo music.


2. Getting Stressed About Grades

Another study-related cause of tooth grinding is stress over tests and grades. In the current economy where good jobs are scarcer, coming out of university with top marks can feel more important than ever. As a result, more and more students find themselves dealing with high levels of stress and anxiety, which can lead to jaw clenching and tooth grinding both at night and during the day. In fact, stress is often the biggest cause of bruxism.


While reducing study stress is often easier said than done, you can take many steps to keep worries at bay. Alongside avoiding procrastination and managing your time well, you can also try breathing exercises, improving your diet, exercising often and talking to a friend or counsellor.


3. Partying Too Much

Considering how overwhelming studying can be, it's no wonder that so many students like to let loose as often as possible by hitting local clubs, bars and house parties. However, being a party animal can lead to a lot of health problems, one of which is bruxism.


Have you noticed your teeth and jaw feeling particularly uncomfortable after nights out? If so, that's because drinking alcohol doubles your chances of grinding your teeth in your sleep. Like caffeine, alcohol continues to affect your system while you sleep, increasing unwanted motor hyperactivity like bruxism.


To reduce your chances of developing or worsening your bruxism, try to keep your alcohol consumption to a minimum. Don't go out to bars and clubs too many nights each week, and when you do, try to drink fewer alcoholic beverages over the course of the night. Just stay on the dance floor or keep the conversation going with your friends, and you won't feel the need to buy so many drinks. As an added bonus, your wallet will thank you too.

If making changes to your student lifestyle doesn't solve your tooth grinding problem, don't hesitate to book a dental appointment with Drs Phoebe and Foley at Family Dental Care. We can take a look at your teeth to determine the cause of your bruxism, provide you with a custom mouthguard and correct any tooth wear caused by your grinding.

Getting older has its benefits. From retirement to cheaper public transport, there are countless reasons for working-age adults to look forward to their golden years.

However, every part of the human body faces new challenges as we age, and the teeth and mouth are no exception.

Here are four common dental problems faced by older adults and what you can do about them.

1. Dry Mouth

One in three seniors suffer from dry mouth, but contrary to popular belief, it is not a normal part of getting older. Dry mouth is a serious condition that results from a lack of saliva. This can be damaging to your oral health, as saliva production is essential for keeping teeth healthy and strong.

Most cases of dry mouth are a side-effect of prescription medication. Older people typically take more medicines on a daily basis, which is one main reason this condition is commonly associated with old age.

Dry mouth can potentially cause tooth decay and loss, so it is important to treat the condition as soon as it becomes evident. Chewing gum can help stimulate saliva production, and over-the-counter saliva substitutes are available to help moisturise the mouth.

Make sure you visit your dentist regularly for a scale and clean, as this will rid your teeth of the bacteria that build up due to a lack of saliva. If you are certain that your dry mouth is related to your medication, consult with your doctor to see if you can switch to another drug.

2. Periodontal Disease

Nearly one in five seniors aged over 65 suffer from periodontal (gum) disease, making it one of the most common conditions among older adults. Periodontal disease is caused by a build-up of bacteria on the teeth, and it commonly manifests in the form of swollen or red gums. More severe cases of gum disease will cause your teeth roots to become exposed, potentially causing your teeth to become loose.

The best way to prevent periodontal disease is to follow a strict oral hygiene regimen. Make sure to brush your teeth twice a day and have your teeth professionally cleaned by your dentist on a regular basis.

In addition, smoking cigarettes can increase your risk of developing periodontal disease by up to six times compared to a non-smoker, so if you smoke, consider quitting.

3. Tooth Erosion

As you age, the enamel on your teeth gradually erodes as a result of normal wear and tear. Tooth erosion is a major cause of sensitive teeth, and the bad news is that worn tooth enamel cannot grow back.

However, there are a number of things you can do to prevent tooth erosion as you enter your golden years.

First, limit your intake of soft drinks, as these contain acids that can wear away your tooth enamel. Second, if you suffer from bruxism (teeth grinding), ask your dentist about getting a night guard to protect your teeth while you sleep. Finally, use a soft tooth brush and do not brush your teeth too harshly, as this can make tooth erosion worse.

4. Mouth Cancer

Thankfully, mouth cancer has a low prevalence, but its consequences are serious enough that you should be aware of this health problem. Older adults are more likely to develop mouth cancer than young people, and men are twice as likely as women to suffer from the disease.

Symptoms of mouth cancer include sore gums, lumps inside the mouth, bleeding from persistent ulcers and difficulty swallowing.

Aside from refraining from tobacco use, there is not much you can do to reduce your risk of mouth cancer. However, the disease can easily be cured if detected early, so next time you visit your dentist or doctor, ask for a quick check-up.

Old age brings a number of oral health challenges not often seen in younger adults. As you age, your oral health becomes more important than ever.
