Dental abscess: warning signs you should never ignore

A dental abscess is a serious bacterial infection. Left untreated, it can spread to the jaw, neck, or brain, with potentially life-threatening consequences. Understanding the warning signs and acting on them quickly is not something to put off until a convenient moment.

What is a dental abscess?

An abscess is a pocket of pus that forms as the body attempts to contain a bacterial infection. In dentistry, there are two main types.

A periapical abscess forms at the tip of a tooth root, usually as a result of decay that has reached the pulp and caused a pulp infection. The bacteria spread through the root canal system to the surrounding bone.

A periodontal abscess forms in the gum and bone alongside the tooth, often as a result of advanced gum disease trapping bacteria in a deep gum pocket.

Both types require professional treatment. Neither will resolve on its own.

Warning signs

Severe, throbbing pain that may radiate to the ear, jaw, or neck.

Swelling in the face, cheek, or jaw. Swelling that is increasing, particularly if it is affecting your ability to open your mouth or swallow, is a sign that the infection is spreading and should be treated as a medical emergency.

A pimple or bubble on the gum near the affected tooth. This is a sinus tract, a channel through which the abscess is draining. Its presence may temporarily relieve pain, but the infection itself is still present and still active.

Sensitivity to heat that lingers long after the stimulus has been removed.

Fever, sweating, or a general feeling of being unwell alongside dental pain. These systemic symptoms indicate that the infection is spreading beyond the local area.

A bitter, foul taste in the mouth that comes on suddenly, which may indicate that the abscess has spontaneously burst.

What to do

If you suspect a dental abscess, contact Berkhamsted Dental on 01442 865 646 immediately. We treat dental infections as a priority.

Do not try to burst the abscess or apply heat to the area; both can spread the infection. Over-the-counter ibuprofen (if appropriate) can help manage pain and reduce inflammation while you wait for an appointment.

If you have significant facial swelling, difficulty swallowing or breathing, or a high fever, go directly to a&e. These are signs of a spreading infection that requires immediate medical attention.

Treatment

Treatment typically involves draining the abscess, prescribing antibiotics, and then addressing the cause: root canal treatment to save the tooth, or extraction if the tooth cannot be saved, followed by a discussion of replacement options, including dental implants.

  • Great service and lovely staff! Emily on reception was fantastic :)

  • Greeted warmly by everyone. Treated respectfully by my dentist with step by step explanations regarding my treatment. Consequently, I was able to feel more relaxed having been reassured that all was going well. Thank you for an excellent outcome.

    Very happy with my Invisalign process with Kish. He kept me well informed throughout and always took time to answer all my many queries. The price was reasonable compared to others in the area and it has all been completed within the original time advised. I'm yet to have my composite bonding done but hope to have a transformed smile in the end. Would thoroughly recommend BDP if you're considering Invisalign.

    I have just completed the main part of my Invisalign journey followed by composite bonding and could not be happier. Having been told by my previous dentist that it wasn’t worth doing ( due to my age and small change I would achieve) I had a consultation with Dr Kish to start a programme of Invisalign to straighten out my front teeth which had moved over time and now had a very slight overlap. Once complete, I saw Dr Ventsi for bonding to the edges of 6 teeth, which, as a heavy tooth grinder, were chipped and uneven. Both Drs were knowledgeable and lovely to deal with. I could not be happier with the result! A little change has made a huge difference !
