Mouth & soft-tissue care · Mayfield, NSW
Blood blisters in the mouth appear suddenly, look alarming and are usually harmless. The ones worth acting on are those that linger, recur or arrive without explanation. MS Dental Mayfield, at 181 Maitland Rd, examines oral blood blisters, identifies what is causing them, and advises on the right course of action for your situation.

The lining of the mouth is thin and richly supplied with small blood vessels. When those vessels break – from a bite, a knock or friction – blood escapes into the tissue just below the surface and forms a raised, dark red to purple dome. That is an oral blood blister.
It differs from an ordinary blister only in its contents: blood rather than clear fluid. Most are soft to touch, mildly tender at worst, and self-limiting. They usually rupture on their own and the surface heals within days.
Several other things in the mouth can be mistaken for a blood blister, and each is managed differently.
Why we examine
Telling these apart reliably requires examination, not description. It is the reason we will not offer an opinion over the phone or from a photograph.
Everyday physical trauma accounts for most cases: catching the cheek or tongue between the teeth, biting into something hard or sharp, a fractured tooth or rough filling edge, a sports impact, a knock during play, or friction from a denture, mouthguard or orthodontic appliance. Very hot food and drink can contribute.
Medications that thin the blood, and conditions affecting platelets or clotting, make blisters more likely and slower to settle. Blisters that appear repeatedly with no injury behind them are the ones that most warrant investigation.
Tongue blisters usually follow an accidental bite, contact with a sharp tooth edge or restoration, or scalding food. They are common, heal quickly and rarely need treatment. When the same spot blisters again and again, the answer generally lies in a nearby tooth surface rather than in the tongue itself.
Blisters inside the cheek most often sit along the biting line. Habitual cheek biting, a sharp cusp, an orthodontic bracket or a poorly seated denture edge are typical causes. Treating the blister without correcting what is rubbing simply means it recurs.
Gums and lips are exposed to toothbrush and floss injuries, sporting impacts and trauma during eating. Lip blisters after a knock are common in children and in contact-sport players. A dark swelling on the gum needs a proper look, since an abscess or another soft-tissue lesion can present in a similar way and requires entirely different management.
Mayfield and the surrounding inner-Newcastle suburbs field a lot of junior and senior sporting teams, and contact sport is a recurring cause of oral blood blisters in our patients. Two patterns come up repeatedly.
The first is direct impact – an elbow, a ball or a fall driving the lip or cheek against the teeth.
The second, and more preventable, is friction from a poorly fitting mouthguard, particularly the boil-and-bite type that shifts during play.
A custom-fitted mouthguard is moulded to the individual’s teeth, stays put, and removes the rubbing at source. For growing children, it needs reviewing each season as the teeth change.
Custom mouthguardsBlood-thinning medications such as warfarin, apixaban, rivaroxaban and clopidogrel, along with regular aspirin use, make small bleeds beneath the mucosa more likely and slower to resolve. Conditions affecting platelet numbers or clotting have the same effect.

Call (02) 4023 3885Examination, not a photo
A description over the phone or a photograph is not enough to identify a lesion. Only an examination can do that.
At our Maitland Rd clinic, an assessment appointment involves:
When it appeared, how it has changed, whether this has happened before, and your medications and medical background.
The lesion and the whole soft-tissue lining – tongue, cheeks, lips, palate, floor of the mouth and gums.
We look for the sharp edge, the fractured tooth, the rough restoration, the mouthguard or the denture doing the damage. For sports players, a poorly fitting mouthguard is a frequent and easily corrected culprit.
Adjusting or smoothing the cause is often the whole treatment. Where an intact blister needs drainage, that is carried out under sterile conditions. Where a procedure requires laser soft-tissue treatment, we arrange it at our Fletcher clinic.
Persistent, recurrent or unexplained lesions are reviewed, and referred to your GP or an appropriate service where further investigation is warranted.
Children develop blood blisters from falls, sport, biting the cheek while eating and knocks during play. Most settle quickly without treatment. Bring your child in if bleeding will not stop, if a tooth was damaged in the same incident, if they cannot eat or drink comfortably, or if blisters appear repeatedly without an injury behind them.
Our Mayfield clinic treats children of all ages, and eligible children aged 2–17 may be bulk billed for some services under the Child Dental Benefits Schedule, subject to their available balance.
Prevention is almost entirely mechanical: repair the chipped tooth, smooth the rough filling margin, adjust or reline the denture, wax over the orthodontic bracket, and replace an ill-fitting mouthguard with a custom one. Eating more slowly and addressing habitual cheek biting both help. Routine check-ups pick up sharp edges before they cause repeated trauma.

Most often an unnoticed minor injury – catching the cheek or tongue between the teeth, a sharp piece of food, a rough tooth or filling edge, or friction from a denture, mouthguard or appliance. Blood-thinning medication and conditions affecting clotting make them more likely. A blister appearing suddenly and repeatedly with no injury behind it should be examined.
Usually, yes. Most rupture naturally within days and the surface heals over within one to two weeks. If yours has not healed in that time, book an examination.
Not routinely. Most need no procedure at all, and the more useful step is correcting whatever is causing the trauma. Where an intact blister is large or interfering with function, a dentist may drain it under sterile conditions. Do not attempt to burst one yourself – it risks infection and a painful ulcer.
Yes. A mouthguard that does not fit properly, particularly a boil-and-bite type that shifts during play, can rub the cheeks, lips and gums. A custom-fitted mouthguard is moulded to your teeth and removes that friction.
Occasional blisters after knocks and bites are normal in active children. Repeated blisters with no injury behind them warrant an examination, both to check for a mechanical cause and to make sure nothing else is contributing.
