ToggleCan Wearing a Night Guard Hurt Your Gums?
Night guards protect your teeth and reduce jaw tension caused by grinding or clenching. However, different factors can cause a night guard to damage your gums. Below, we explain these factors and show how each one can affect your gums:
Material Allergy
A material allergy is one reason night guards damage gums. It can make gums red, swollen, and sore. If it continues, the gums may pull back, expose the roots, and lead to sensitivity and cavities.
Low Material Quality
Low‑quality guards often feel rough and do not spread pressure evenly. This can irritate gum tissue, wear down enamel, and cause small cracks or sensitivity in teeth.
Poor Fit
A poor fit often makes night guards damage gums. A guard that is too tight or too loose can press on or rub the gums. It can also create uneven pressure on teeth, which may thin enamel and cause cracks.
Poor Cleaning Habits
If a guard is not cleaned well, bacteria and plaque build up. These germs stay against your teeth and gums for hours while you sleep, which can weaken enamel, cause cavities, and irritate the gums.
Old or Damaged Night Guards
Old or cracked guards can have rough edges that rub or scratch your gums. They can also change your bite, chip enamel, cause sensitivity, and make teeth wear down faster.
