Dental Treatment Complications in Kitchener

Most dental treatment goes the way it’s supposed to. You get numb, the work is done, you’re a bit sore for a day or two, and then you forget about it. Every so often, though, something doesn’t settle. The pain gets worse instead of better, a temporary crown pops off, or a bite feels wrong days later. At Fairway Dental in Kitchener we help patients with treatment complications, including after work done at another office. This page helps you sort out what’s a normal part of healing and what needs a dentist’s attention.

Normal recovery versus a real problem

Some discomfort after dental work is expected. Teeth and gums have been handled, numbed and sometimes drilled, and the tissue needs time. The pattern is what tells you whether things are on track.

Usually normal

Soreness at the injection site for a day or two
Mild sensitivity to cold for a few weeks after a new filling
Tenderness when biting for several days after a root canal
Some swelling and oozing for the first day after an extraction
A jaw that feels tired after a long appointment with your mouth open

Worth a call

Pain that’s getting stronger after the third day instead of easing off
Swelling that appears or grows a few days after treatment
A fever, or a foul taste or smell from the area
Numbness that’s still there the next day
A tooth that feels high, so you hit it first every time you close
A temporary filling or crown that has come out or broken

Trust your gut here. You know your own mouth. If something feels off, it’s fine to phone and describe it.

Complications we see and treat

Dry socket after an extraction

After a tooth is pulled, a blood clot forms in the socket and protects the bone while it heals. If the clot breaks down or gets dislodged, the bone is exposed and the result is a deep, aching pain that often spreads to the ear. It usually shows up two to four days after the extraction. Smoking, vaping and drinking through a straw raise the risk. We clean the socket and place a soothing dressing, which often brings relief quickly.

Infection

Infections can follow extractions, root canals or deep fillings. Signs include swelling, throbbing pain, a pimple on the gum or a bad taste. Treatment depends on the source and may involve draining, cleaning the area, adjusting or redoing the work, and sometimes antibiotics.

A bite that’s too high

When you’re numb it’s hard to tell exactly how your teeth fit together. A new filling or crown that sits slightly high takes the full force of every bite and can become very sore. The fix is simple: we mark where the teeth touch and smooth the high spot. It usually takes a few minutes.

Lost or broken temporaries

Temporary crowns and fillings are meant to last weeks, not years, and sticky foods can pull them off. A tooth left without its temporary can become sensitive, shift slightly or break. We can recement or remake it so the tooth stays protected until the final restoration is ready.

Lasting numbness

Freezing usually wears off within a few hours. Rarely, especially after lower wisdom tooth removal, a nerve can be irritated and leave tingling or numbness in the lip, chin or tongue. Most cases improve over weeks to months, but it should be checked and monitored.

Ongoing pain after a root canal

Some tenderness is normal. Pain that persists or returns can mean a canal was missed, the tooth has a crack, or infection hasn’t fully cleared. The dentist will examine the tooth and take X-rays to work out why.

Sensitivity that won’t fade

Cold sensitivity after a filling usually fades within a few weeks. If it’s getting sharper, lingers long after the cold is gone, or turns into a throb, the nerve may be inflamed and the tooth should be looked at.

What to do right now

If there’s bleeding after an extraction, bite firmly on gauze or a damp black tea bag for 30 minutes.
For swelling, use a cold pack on the outside of the face in the first day or two.
Take pain relievers you normally use safely, as the label directs.
Keep the area clean with gentle warm salt water rinses unless you were told otherwise.
If a temporary comes off, keep it, and avoid chewing on that side. Pharmacy temporary cement can hold it for a short time.
Don’t stop prescribed antibiotics early, even if you feel better.

Go to a hospital emergency department if swelling is affecting your breathing or swallowing, if bleeding won’t stop after 20 minutes of firm pressure, or if you have a high fever with facial swelling.

Getting help after treatment at another office

We regularly see people whose original dentist is away, booked up or too far to get to quickly. We’ll focus on getting you comfortable and dealing with the immediate problem. With your permission we can contact the office that did the work, ask for X-rays or notes, and send them a summary afterwards so your regular dentist knows what happened. Bring any paperwork or medication lists you were given, including the name of any antibiotic or pain medication prescribed after the procedure.

Keeping track of symptoms

When you call, the more specific you can be, the faster we can help. It’s worth jotting down a few notes, even on your phone:

The date of the original treatment and what was done
When the new symptom started and whether it’s getting better, worse or staying the same
What triggers it: biting, cold, heat, lying down, or nothing at all
Your temperature if you feel feverish
Any medications you’ve taken for it and whether they helped

A photo of swelling taken at the same time each day can also show us whether it’s going up or down, which is surprisingly hard to judge in the mirror.

What the visit involves

We’ll ask what was done, when, and how the symptoms have changed since. The dentist examines the area, checks your bite and usually takes an X-ray. Then they’ll explain what they think is going on and what the options are. Some complications are sorted out in one short visit. Others need a follow-up to make sure healing is back on track.

Questions we often get

How long should I wait before calling?

If pain is clearly getting worse, or you have swelling, fever or a lost temporary, call now. If it’s mild and slowly improving, give it a few days, but don’t hesitate to ask.

Does a complication mean the treatment was done badly?

Not necessarily. Bodies heal differently, and some problems, like dry socket, happen even when everything was done carefully. The goal is to fix the problem, not assign blame.

Can a complication be prevented?

Following aftercare instructions helps a lot. Avoid smoking and straws after extractions, keep temporaries away from sticky foods, and call early when something feels wrong.
