Injuries to the soft tissues of the mouth — the gums, lips, cheeks, tongue, and the floor of the mouth — are surprisingly common and often more alarming in appearance than they are serious in reality.
At the same time, some soft tissue injuries are genuine dental emergencies that require prompt professional assessment. Knowing which situation you’re dealing with can make a significant difference to your outcome and your anxiety levels. This guide is written for patients in Woking and the surrounding areas of Surrey who are unsure how to respond to a mouth injury.
Types of Soft Tissue Mouth Injury
Soft tissue injuries in the mouth generally fall into the following categories:
- Lacerations: Cuts to the lip, cheek, tongue, or gum, often caused by a fall, a blow to the face, or biting down hard on the cheek accidentally.
- Puncture wounds: Caused by sharp objects, including pen tops, cutlery, or dental instruments in rare cases of accidental contact.
- Contusions: Bruising to the soft tissue without a visible break in the surface, often accompanied by swelling.
- Avulsions: More serious injuries where a section of soft tissue is partially or completely torn away.
- Burns: Thermal burns from very hot food or drinks, or chemical burns from substances like aspirin placed directly on the gum.
Most lacerations and contusions affecting the lips and cheeks can be assessed at a dental practice. Injuries involving the throat, the floor of the mouth, or significant tissue loss are better assessed at an A&E department, where surgical expertise is available if needed.
First Aid Steps for Mouth Injuries
Before you reach us, there are straightforward steps you can take to manage the injury and reduce bleeding:
- Apply firm, gentle pressure to the wound using a clean cloth or gauze for at least 10 minutes without lifting
- If the wound is on the lip or cheek externally, a cold compress applied to the outside can reduce swelling
- Rinse the mouth gently with cool water to clear blood and debris — do not use alcohol-based mouthwash
- Avoid eating or drinking anything hot until you’ve been assessed
- Sit upright and tilt the head slightly forward to prevent blood from going down the throat
Bleeding from oral soft tissue injuries tends to look more dramatic than it is because saliva dilutes blood, making wounds appear to bleed more heavily than they actually are.
When to Go Directly to A&E
Certain features of a mouth injury require emergency medical rather than dental care. These include:
- Bleeding that does not slow or stop after 10 to 15 minutes of continuous pressure
- A wound that is wide or deep enough that it may require stitches
- Signs of a broken jaw — inability to close the mouth properly, asymmetry of the face, or significant pain when moving the jaw
- Injury to the throat or back of the mouth, particularly with swelling that could affect breathing
- Loss of consciousness, even briefly, following a blow to the head
And if there is any question about an airway injury, do not wait — call 999 immediately.
When a Dentist Is the Right First Call
If the bleeding is controlled and the injury is limited to the gums, lips, or cheeks without deep penetration, a dentist is the appropriate first point of contact. We can assess whether any underlying teeth have been affected — which is often overlooked in the immediate aftermath of a soft tissue injury — and provide treatment or advice as needed.
In our experience, patients who attend a dental practice after a soft tissue mouth injury frequently discover that a tooth has also been loosened or chipped as a result of the same impact, something that would have gone unnoticed until it caused further problems later.
We can also assess whether a minor laceration requires treatment at all. Many small gum lacerations heal without suturing, and attending a dental appointment allows us to confirm this rather than leaving you to wonder.
Specific Injuries and How We Manage Them
| Injury | Initial Action | Likely Dental Management |
|---|---|---|
| Gum laceration | Pressure and rinse | Assessment; suturing if deep |
| Bitten tongue or cheek | Pressure; cold compress | Usually self-healing; review if swelling persists |
| Lip laceration (internal) | Pressure; cold compress | Assessment; suturing if gaping |
| Gum bruising/haematoma | Cold compress | Monitor; drain only if indicated |
| Denture-related ulcer or injury | Remove denture | Adjustment or repair of the denture |
Aftercare for Soft Tissue Injuries
Once a soft tissue mouth injury has been assessed and any necessary initial treatment carried out, the healing process benefits from straightforward aftercare. A lukewarm saline rinse — made by dissolving a teaspoon of salt in a glass of warm water — used two to three times daily helps keep the wound clean and reduces infection risk.
The NHS guidance on mouth injuries and ulcers provides useful supplementary information on supporting healing at home. Avoid tobacco products and alcohol during the healing period, as both impair soft tissue recovery.
But don’t assume that discomfort that increases rather than decreases after the first 24 hours is simply part of the healing process — worsening pain or swelling after a mouth injury should prompt a call to the practice.
