Pain that is building
Note when it began, whether it comes without eating, whether it wakes your child, and how pain relief is working. Increasing pain is a reason to call promptly rather than wait for a routine slot.

A swollen cheek over a baby molar raises two questions at once: how urgent is this, and can the tooth be saved? For households in Caledon, we explain when to phone, when to seek emergency care instead, and how a pulpectomy might fit once things are stable.
Facial swelling from a baby tooth usually means the pulp inside has died or become badly inflamed, and infection has reached the tissues around it. Urgent assessment comes first. Once the situation is under control, the dentist may discuss a pulpectomy for a tooth that is still restorable: removing the diseased pulp from crown and canals, cleaning the spaces, and filling them with a material made for primary teeth.
That procedure is more extensive than a pulpotomy, where healthy tissue in the roots is kept. It also isn’t an adult root canal in a smaller tooth. Primary roots are designed to dissolve as the permanent tooth beneath them develops, which matters all the more when infection has been close to that developing tooth.
After a swelling episode, the question of whether to keep the tooth deserves a calm, unhurried look. From Bolton or one of Caledon’s other villages, you can expect us to weigh the infection history, the roots, the remaining crown, your child’s health and other needs. Removal, a different procedure or a pediatric specialist may be the better route, and we will tell you if so.

Our advice draws on your description, an examination and suitable X-rays. Swelling that has gone down by the time of the appointment is still an important part of the history.

A gum bump or mild puffiness needs prompt dental advice. Swelling that spreads quickly, reaches the eye or neck, or comes with trouble breathing or swallowing needs emergency medical care. Don’t squeeze anything.
Once the infection is managed, remaining structure and root condition determine whether a pulpectomy makes sense. Ask how near the tooth is to natural loss and how the infection affected the roots.
Call for prompt dental advice about suspected infection. Breathing or swallowing difficulty, rapidly spreading facial swelling, or a seriously unwell child needs emergency medical care immediately, at the nearest hospital.
In a suitable primary tooth, a pulpectomy targets the diseased pulp that fed the infection, with the aim of keeping a working tooth in place. Root findings matter a great deal. Extraction should be considered alongside it, especially after a significant infection.
Treatment can’t promise a good outcome. Ask about this tooth’s prognosis, what canal treatment cannot do, and what would happen if swelling came back. Medicine may calm an episode, but the source inside the tooth still has to be addressed through treatment or removal.

Ask what this tooth would contribute before it is naturally lost, such as chewing and supporting developing teeth. Consider what further treatment would mean for a child who has just been through a painful episode.
The broken or decayed surface needs a proper final restoration once the canals are treated. Ask what is planned and whether each stage is booked, since a leaking repair can let problems return.
Notes and appropriate X-rays from the episode give a baseline for later comparison. Ask how review visits will be timed, and keep track of any changes you notice at home.
Visit timing and length depend on the infection, the tooth and your child. We will explain the comfort approach and whether treatment would be safer in another setting.
The clinician first addresses any active infection, then reviews symptoms, examination, root findings and restorability. Alternatives and the outlook are discussed. Ask whether a specialist should be involved given the swelling.
Local anaesthetic and isolation are arranged to suit the tooth. Your child should know how to signal discomfort. Mention past difficult visits, health conditions or support needs before the appointment.
Diseased pulp is removed, the canals are cleaned with suitable techniques, and a resorbable filling designed for primary teeth is placed. The approach depends on the tooth and the infection history.
A final restoration closes the tooth; for a back molar this is often a crown. Where indicated, an X-ray records the finished canal work. Before you leave, confirm any remaining visit, the home-care instructions, and the date when the tooth, the gum where the swelling was, and the restoration will be rechecked.
Ask what your child may feel after the treatment provided. Make sure every caregiver knows the food limits, medicine instructions and next appointment.
Supervise your child so they don’t bite a numb lip, cheek or tongue. Follow the eating and drinking advice. Any pain medicine should be appropriate for your child, used as the treating professional directs.
If treatment is staged, protect the temporary filling as instructed and come back on schedule. Call promptly about a lost filling, loose crown or food trap. Skip household glue, and don’t delay completion because the swelling has settled.
Feeling well is encouraging but doesn’t confirm that the infection has fully resolved. Attend every review and X-ray recommended, even when the cheek has looked normal for weeks, keep up home care, and ask about preventing decay in the other teeth so another episode is less likely.

Bring any notes from urgent visits, prescriptions or X-rays. They help us understand what happened and plan the next step.
Call our Bronte Street practice if your child has swelling, pain or a pulpectomy recommendation. We can advise on urgency, explain the assessment and the reasons a baby tooth might be retained or extracted, and say when referral fits better.
Treatment depends on examination and appropriate X-rays. Active swelling or rising pain should always be discussed by phone first.
