Brief reactions to cold, air, or brushing
Say which triggers you notice and whether one tooth or several respond. A short reaction is still worth having checked if it is new, building, or making you hurry through part of your brushing.

You whitened for a wedding photo, and now every cold sip stings. Or nothing changed at all and the twinge just appeared. From Mississauga, you can have the sensitivity assessed so treatment follows the real cause, not a hunch.
Whitening is one of the first things people suspect when their teeth turn touchy, and sometimes the timing really does fit. Still, a coincidence is easy to mistake for a cause. Decay, a cracked tooth, a worn filling, or receding gums can all start to make themselves felt during the same weeks you happened to be using strips or trays.
So the sensible move is to pause the product if it seems to be the trigger and have the teeth examined. Our Bronte Street team will ask what you used, how often, and when the sensation began, then look at the teeth and gums for the source. Exposed dentin is a frequent finding, but it is not the only one, and a new toothpaste cannot sort that out for you.
Describe ordinary moments rather than staged tests: the iced coffee on the way to work, the brush along the gum line, the first bite of something sweet. Mention whether it is easing since you stopped whitening or carrying on regardless. That gives the dentist what is needed to explain the cause, recommend fitting care, and set a point to check progress.

Where you feel it, what starts it, and how long it continues are the facts that help most. Share them plainly and let the examination supply the diagnosis.

Discomfort that carries on after the drink, disrupts sleep, or arrives without a trigger may need a sooner visit and a different line of investigation. At that point, switching to a stronger paste is not the logical next step.
Report whitening products, recent dental work, a new rinse or toothpaste, an injury, or a change in your bite. The timing may be relevant. It is not conclusive on its own, so the tooth still needs to be examined.
Contact us promptly about swelling, a broken tooth, real pain when you bite, or symptoms that are getting worse. If you are already booked for a regular checkup, tell us about this so we can decide whether you need to come in sooner.
When the protective covering over dentin thins or is lost, temperature and touch can reach the inner tooth more easily, and sensitivity is the result. Other dental problems can feel very similar, so an examination is needed to tell them apart. Treatment may then be a home product, a professional application, or care directed at one specific problem.
Improvement is possible, but it may be gradual and is not guaranteed to last. Ask what the chosen approach is meant to change, how to use it, and when you will review it together. You should also know what to do if the discomfort holds steady or starts to behave differently.
Patient information: ADA MouthHealthy — sensitive teeth and possible causes
Bring the name of the whitening product and your schedule. The dentist can consider it alongside the examination findings and advise whether and how to continue, instead of leaving you to decide by trial and error.
If decay, a damaged restoration, or another concern turns up, it can be treated directly rather than masked. Ask how each recommendation relates to what was found, so you understand what the treatment is for.
Avoiding a sore area while brushing makes care harder over time. Tell us where the routine is uncomfortable so technique and tools can be adjusted. You want cleaning you can manage while the cause and your response are followed.
Which tests make sense depends on what the dentist finds. If you are anxious about discomfort, say so, and each step can be talked through before it begins.
Explain when the sensitivity started, what triggers it, where it is, and how long it lasts, along with any whitening, night pain, or recent dental work. If you cannot locate it precisely, that is expected and fine.
The dentist checks the relevant surfaces, any restorations, and the gum tissue. Tests or imaging may be suggested to clarify the source. Ask what each is meant to show, and tell the clinician whenever you would like to pause.
You will hear what has been established and what remains unclear. If a conservative option suits the findings, the team explains how to use and monitor it. If a tooth needs treatment, ask about options, limitations, and timing.
Confirm your home routine, any treatment provided, whether and when whitening may resume, and when to report back. Ask which changes should prompt an earlier call. Any trial should have a defined purpose and review date.
Use the instructions for your diagnosis and the specific product or procedure involved. What follows a new filling is not the same as what follows a desensitizing toothpaste.
Touching the tooth with something cold to check on it only keeps it irritated. Brush with a soft brush and the technique discussed, without extra pressure on the tender area. Tell us if it is still hard to clean.
A desensitizing toothpaste may take consistent use before you can judge it. Follow the directions rather than combining treatments or using more. Keep whitening on hold until you have advice, especially if it seemed to start the problem.
If useful, record the trigger, how long the feeling lasts, and whether eating and brushing feel easier. There is no need to provoke the tooth. Call us if pain worsens, begins without a trigger, or is not improving as expected.
Ask about whitening, triggers, products, and how the response will be reviewed. Sensitivity is a symptom, and it can point to more than one problem.
Phone the clinic with a quick description of your sensitivity, and we will arrange an assessment. Let us know if pain lingers, appears without a trigger, or began after whitening or recent treatment so we can plan the right next step.
Treatment depends on the cause. New swelling or significant, worsening pain should be reported promptly rather than handled with products alone.
