Treatment for a Dental Infection in Old Milton

An old crown that suddenly feels tall, or a tooth treated years ago that aches again, can point to an infection under existing dental work. Call us from Old Milton and we will talk through the examination, the options and the follow-up involved.

When older dental work starts to ache

Many mouths carry history: a crown from a decade ago, a large filling, a tooth that had a root canal before you moved to Old Milton. Trouble around that work can show up quietly. The tooth may feel slightly high when you close, sore under pressure, or surrounded by gum that is puffy and tender. A taste you can’t brush away, or a spot that drains near the root, can also appear.

None of those signs settles the question by itself. Pain under a crown could come from the nerve, from the tissues around the root, from a crack, or from a gum problem nearby. Treatment that works for one cause won’t help another, which is why identifying the source comes before choosing the next step.

Our Bronte Street practice sits close to Milton’s historic downtown, so a phone call is usually the simplest start. Tell us what the tooth has been through, what is different now and whether you feel generally unwell. We can discuss availability, what an assessment covers, and when urgent medical care would be the better route. Bring any records you have, but don’t delay calling to find them.

Useful background for your call

Past treatment, present symptoms and how you feel in yourself

We learn the most from the story over time. Let us know what work the tooth has had and roughly when, any medicine you have started, and whether another dentist or doctor has already seen it.

A treated tooth that hurts again

Describe whether the ache comes on by itself, builds when you chew, or lingers after hot drinks. Note any crown that feels loose, a filling edge you can catch with your tongue, or a recent knock. How strongly it hurts cannot separate infection from a crack or other problem, and each of those still needs care.

Swelling or a drainage spot near the root

Show us where it began and tell us if it is spreading, returning or reaching toward the cheek. A gum spot that empties and fades can return weeks later, so it still deserves a look. Please don’t press on it or try to open it at home; let the source be assessed properly instead.

General illness or medical changes

A fever, feeling washed out, stiffness when opening, or trouble eating all matter. So do newer health conditions or medicines, especially anything that affects how you fight infection, such as certain treatments for cancer, arthritis or diabetes. Raise these on the first call because they can alter how quickly and where you should be seen.

If breathing is difficult or something feels life-threatening, call 911. Trouble swallowing, severe or quickly spreading swelling of the face or mouth, swelling around an eye, or any change in vision needs emergency assessment immediately. An online form is not the right way to raise these.

A plan worth having

Easing the ache is the start. Finishing the work is the point.

Older restorations can make planning more involved, so it helps to know exactly what is being addressed. Is this visit to calm the tooth, to treat it fully, or to arrange a specialist opinion? Asking that plainly guards against the common pattern where relief arrives and the remaining steps fade from view.

It also helps to understand what the tooth can realistically support from here. A tooth with a crown and an earlier root canal may have fewer options than an untreated one, or it may still be a good candidate for retreatment. Ask about keeping it, how many visits are likely, recovery, fees and time off. Those questions belong in the conversation even when you are uncomfortable.

Findings explained in plain terms

Ask which tooth or tissue seems responsible and what in the examination or X-rays suggests it. Earlier records can help with comparison. Where the source is still uncertain, you should hear what more information is needed before an irreversible step is recommended.

Knowing which part is temporary

A first visit may relieve pressure while definitive care is still to come. Ask what has been done, what remains, and the timeframe for it. A written summary helps if you are tired or coordinating appointments with family or caregivers.

Follow-up you can keep

Confirm who to contact if symptoms change, how a referral will be organised and when the area should be checked again. Tell the team early if mobility, transportation, scheduling or cost might interrupt the plan, so arrangements can be made before a visit is missed.

How the visit usually unfolds

From history to a decision you understand

Have a list of your current medicines and allergies, plus any notes about previous treatment on the tooth. Let the clinician know about pregnancy, immune concerns, blood thinners or past difficulty in the dental chair so the assessment can account for them.

  1. Start with the timeline and your health

    The clinician will ask when it began, how it has progressed and whether you have noticed swelling, discharge, fever or trouble opening. Mention medicine you have taken and who recommended it. Part of this step is deciding whether the problem suits a dental setting or needs urgent care elsewhere.

  2. Look at the tooth, its restoration and its neighbours

    Examination may cover the crown or filling, the teeth on either side, the gum, and appropriate tests or images. Let the clinician know if a test is sore. Old work can hide what is underneath, so the aim is to connect your history with the findings rather than react to the swollen area alone.

  3. Weigh the treatment options and their limits

    Care could involve drainage, root canal treatment or retreatment, gum therapy, or extraction, depending on the diagnosis. Ask about alternatives, how likely the tooth is to last and whether an endodontist or other specialist should be involved. Comfort and consent are discussed before any procedure.

  4. Agree on medicine, next visits and review

    If a medicine is recommended, ask its purpose and how it fits with what you already take. Antibiotics are not a default replacement for treating the source; they suit particular situations such as signs of spread or certain health risks. Leave knowing what to do if things worsen.

Once the first step is done

A quieter tooth still needs its next appointment.

Aftercare follows the procedure and findings. Instructions after drainage, root canal work, gum treatment or extraction differ, and a restored tooth may need extra care until its final crown or filling is placed. Ask for guidance that applies to you.

Medicines exactly as prescribed

Follow your clinician’s directions and check with a pharmacist about interactions with your regular medicines. Avoid leftover antibiotics, shared prescriptions and extra doses of pain relief. Report a suspected side effect promptly, and get emergency help for breathing trouble or a serious allergic reaction.

Gentle with the treated tooth

Ask how to chew, brush and clean around it, especially under a temporary crown or near an extraction site. Avoid testing it on hard food. If a temporary restoration loosens or falls out, or the instructions don’t make sense, contact the treating team.

The visit that completes the work

Check whether a further root canal appointment, a new permanent crown, a gum review or a referral is still outstanding. Report returning pain or swelling instead of assuming it is part of healing. If you can’t attend, call to reschedule rather than leaving the tooth half-treated.

Matching care to the cause

Why the same ache can lead to different treatment

Ask what each route would achieve and what it would leave still to do. The choice rests on the diagnosis, the state of the tooth and its support, and your preferences once the facts are clear.

When the tooth is restorable and the canals are the source

Root canal treatment or retreatment, then restoration

Treatment inside the tooth may be advised for a first infection, or retreatment where earlier root canal work has failed. Ask about the complete plan, including a new crown or filling and whether a specialist should assess it. The canal work and the restoration go together, and how well it lasts depends on individual findings.

When the source lies around the tooth

Treatment for the gum and supporting tissues

An infection in the gum or bone around a tooth may need local care and a plan for the underlying gum condition. Ask how support will be measured and reviewed. Tenderness near a crowned tooth does not automatically mean the root canal is at fault.

When keeping the tooth isn’t sensible or care is complex

Extraction or referral

Removal may be suggested if the tooth is cracked, poorly supported or can’t be predictably restored. Ask why, what the procedure involves and how the space might be managed. If another provider is needed, clarify the urgency and what to do while the referral is arranged.

Old Milton questions about infection

What to expect when a familiar tooth becomes a problem

Only an examination can tell you what is going on. These answers may help you prepare, but a worrying change deserves a phone call rather than a match against a web page.

(905) 876-4488
Can a tooth that had a root canal years ago become infected again?
It can. Bacteria may re-enter through a leaking restoration, a crack or a canal that was hard to reach. Bring any records you have and explain when the original treatment was done so the clinician can assess the tooth and the tissues around it.
Why does my crowned tooth feel high when I bite together?
Pressure from inflammation around the root can make a tooth feel raised, though a loose crown or bite change can do the same. It is worth having it checked, especially if tenderness, swelling or a bad taste comes with it.
Do I need to stop my blood thinner before infection treatment?
Don’t stop or change it on your own. Tell us what you take and who prescribes it. The clinician can plan around it and, where needed, coordinate with your physician or pharmacist before a procedure such as an extraction.
If the swelling on my gum drained by itself, can I cancel the assessment?
Drainage often brings relief without removing the cause. Keep the appointment and describe the full history, including how large the swelling was. Avoid squeezing the area to keep it empty.
Is an extraction always necessary for an infected crowned tooth?
No. Some can be retreated and fitted with a new crown, while others have cracks or bone loss that make keeping them unwise. Ask what the findings show and the realistic outlook for each option before deciding.
Could an infection affect a denture or bridge I already wear?
It may involve a tooth supporting a bridge or partial denture. Mention any appliance when you call and bring it to the visit. The plan for the infected tooth may also need to account for how the appliance is held in place.
