Do you grind your teeth at night? Being a grinder sometimes means that you’re too ashamed to give one of those flashy full mouth smiles because your disfigured teeth are suddenly bare for everyone else to see.

What are the side effects of  night mouth guards?

Dental mouth guards are a form of medical treatment, and with any treatment there are those who experience side effects. 

  1. Tooth movement and bite changes – Dental night guards are designed to work by offering a layer of protection between your upper and lower teeth.  However, because of the pressure that is placed on the guard, this can also put pressure on your jaw. Prolonged periods of wearing a dental guard could cause your teeth to move slightly which will affect your bite.
     
  2. Untreated Sleep Apnoea – There are dentists who disagree completely with the use of night guards as they argue that using one doesn’t offer a solution, but helps to mask the under-lying cause of the grinding – sleep apnea.  Sleep apnea is when someone stops breathing during sleep, however, studies have also shown because of how the jaw is affected it can result in grinding.
     
  3. Choking or swallowing – not all guards will stay in place and many are fearful that this can result in choking if they are swallowed

  4. TMJ (Jaw Joint) and muscle discomfort – Most dental night guards work by moving your lower jaw forward, so that when you sleep you’re less likely to grind your teeth.  However, by doing this, there is a risk that you could experience TMJ (jaw joint) and muscle discomfort.

  5. Tooth Discomfort – When using a dental night guards, it is possible that you will experience some element of tooth discomfort.  This has been a common complaint, but it doesn’t cause any long term damage to your teeth and can be resolved by having the night guard adjusted where possible.

What are the different types of mouth-guards?

If you’re in the market for a night guard, then you will soon discover that there a different types, three to be exact.  Each type of mouth guard comes with it’s own pros and cons.

1) Dental Lab/Custom-made

To get a custom-made dental night guard will require a trip to the dentist.  All they’ll do is get you to bit down into a tooth mold, which will be sent off to a dental lab where they make your mouth guard.

2) Boil and bite

Basically, you boil the night guard material to soften it, pop it in your mouth and then bite down so that it molds to your teeth.

Pros

  • It’s molded to your teeth – boil and bite allows you to create your very own custom-made night guard
  • Much cheaper than custom-made – the price itself varies, but as you don’t need to go to the dentist to get one your costs will be significantly reduced

Cons

  • Lower quality – lower costs equals lower quality.  If you grind hard enough in your sleep you could end up biting through the material
  • Not quite custom-made – although they are are custom-made, they’re also not custom-made.  In other words they are customized to your mouth but not to all of your teeth
