How Can Grinding Teeth Cause Tooth Pain – Surprising Reason!

Grinding teeth is more common than you think and is classified as a sleep disorder which ranks 4 on the international classification of sleep disorders (ICSD) right after sleep, talking and snoring.

But the question is: Can Grinding Teeth Cause Tooth Pain?

The simple answer is YES

Grinding the teeth can cause hypersensitivity to hot and cold sensations and I don’t know about you but it causes a massive pain all around my mouth.

More severe cases of Bruxism can lead to teeth fractures and loss of teeth. Sometimes the teeth become misaligned and loose which can cause tooth pain.

The worst is when you have a toothache and a headache at the same time, it can make it unbearable to live. If you grind your teeth regularly you probably know what I mean.

How Does Teeth Grinding Occur?

can grinding teeth cause tooth pain

Did you know that around 85-90% of the general population grind their teeth at some point during their life but it’s only 5% who will develop it as a clinical condition!

Some studies have suggested that women are more commonly diagnosed with Awake bruxism more than males are but when it comes to Sleep bruxism, the statistics are equal for both genders.

Let’s start with the most common problem that leads to Teeth Grinding which is:


Yup this is the major cause of Bruxism and accounts for the majority of grinding teeth patients.

The stressful lifestyle and emotional stress can lead to depression and anxiety which causes havoc on the brain and in turn can lead to this bad habit which some suggest is subconsciously controlled, but more studies are still ongoing to see if this is actually the case.

Clinical studies have suggested that stress is the major reason people seek medical advice and with numbers between 50-70%, it’s quite serious.

Genetic Factors

This is another aspect that plays a role in teeth grinding. Although not as significant as stress it is reported to account for 21-50%.

This is how many people have this condition who have a direct family member who suffered from bruxism as a child.

This shows there is a possible genetic link which needs looking at into more detail.

Occlusal Interference

It sounds complex but all it means is that there is a problem with the structures of the teeth which leads to misalignment and bite issues.

I personally have a slight problem where my top teeth don’t make proper contact with the bottom teeth.

I believe this is also the reason why my 2 top front teeth have little indentations at the end of them.

Which is More Dangerous: Sleep Or Awake Bruxism?

According to the journal: Psychosocial Aspects of Bruxism, Grinding teeth when sleeping is the most dangerous type because of the rhythmic masticatory muscle activity.

The masticatory muscles contribute to the movement of the jaw and are one of the major muscle groups in the head. They can be divided up into the following:

  • Masseter – Elevates the lower jaw to help close the mouth.
  • Temporalis – Elevates the lower jaw to help close the mouth. Also, retracts the jaw, pulling it posteriorly.
  • Medial pterygoid – Elevates the jaw to help close the mouth.
  • Lateral pterygoid – Acting bilaterally, the lateral pterygoids protracts the lower jaw pushing it forwards. Unilateral action produces the ‘side to side’ movement of the jaw.

Some Common Symptoms You Need To Be Aware Of With Teeth Grinding

The most obvious one is grinding the teeth which is accompanied by a distinct sound that usually awakens the partner in bed.

Headaches are a major sign especially if it’s in the temporal zone when you wake up in the morning.

Tooth pain can be another major sign especially if you notice it getting gradually worse and worse. It’s mainly because of the hypersensitivity that has gradually gotten worse as your bruxism has become worse.

Sometimes the teeth grinding can get so bad it shifts teeth out of their original place and causes instability and possible tooth loss.

The Signs are sometimes obvious but other times they can be obscure. Here is the list of the most common ones:

  • Abnormal tooth wear
  • Tongue indentations
  • Gum recession
  • Increase in muscle activity (this is recorded by the polysomnograph)
  • Hypertrophy of masseter muscles
  • Reduction of salivary flow
  • Breakage of fillings and/or teeth
  • Limitation of mouth-opening ability

Can Teeth Grinding Be Fixed?

Most of the time adults don’t have a severe enough case of bruxism to warrant therapy but if your someone who falls into the 5% of people who are classed as high risk then there are some treatment options you can look into.

If you suffer from day time bruxism, habit/behavioural therapy has been suggested to help leave teeth separated.

But if you suffer from sleep bruxism, it has been recommended that sleeping flat on the back without a pillow could help.

Some have even claimed autosuggestion that “I will not clench my teeth while asleep” or by positive posthypnotic suggestions can do wonders.

Cognitive behavioural therapy is another possible direction you can go into but it could take a while before you master this technique.

These are all psychological care treatments but sometimes this is not enough which is why you can opt for medical treatment in the form of Botox injections.

However, there is only one randomised trial that has been carried out which reported the reduction of myofascial pain symptoms.

It was only based on thirty people who received this injection which by all accounts is far too low of a number for any significant conclusions to be made.

There are studies that are currently underway but it could take a while before proper results and conclusions can be generated.

In general, medications aren’t very effective for treatment of bruxism, and more research is needed to determine their effectiveness.

Mouth Guards: The Most Common Treatment Option

Important Note: these methods may prevent or correct the wear to your teeth, but may not stop the bruxism

Mouth guards help to evenly distribute the pressure across your jaw and help to create a barrier between your upper and lower teeth.

This will stop your teeth from getting damaged any further and can help to reduce the noise of clenching at nighttime while you sleep.

They’re made from rubber or plastic and can be made by your dentist to fit your mouth.

You can also get mouth guards from your local pharmacist, but it’s unlikely to fit as well as a custom-made one.

But if you go online and search for mouth guards for bruxism you will find a wide range of options some of which are excellent and don’t cost as much as a custom-made guard.

Grinding teeth does cause tooth pain because the structures of your teeth are being disrupted. Hypersensitivity is one of the major causes of tooth pain because your teeth react harshly to hot or cold sensations.

More severe cases of bruxism can lead to teeth becoming fractured and eventually falling out.

The main treatment options for this is based on behavioural change rather than medication.

Subliminal messages and cognitive behaviour therapy are the more common means but sometimes this can take a while before you stop grinding your teeth.

The most popular method of controlling teeth grinding is using a mouth guard which will protect your teeth from further damage while you sleep.

You can get custom fitted ones from your dental specialist but they can be expensive and the ones you get online are cheaper and do just a good a job.
