Comes and goes in a moment
A sharp response to cold, air, or brushing that fades right away is worth noting, along with whether it affects one tooth or several. Book a check if it is new, increasing, or getting in the way of cleaning.

A quick twinge is one thing. An ache that hangs on after your tea, or nudges you awake at night, is another. Coming from Acton, you can tell us how your sensitivity behaves and have the tooth examined before any treatment is chosen.
One of the most useful things you can tell a dentist is what happens after the trigger goes away. Some teeth flash and settle almost instantly. Others keep throbbing for a while, or begin aching at night with nothing cold anywhere near them. Those differences help decide how soon you should be seen and what the examination needs to look for.
The causes behind sensitivity are varied. Exposed dentin is common and often produces a brief response, but decay, a cracked tooth, a problem with a filling, inflammation inside the tooth, or a gum condition can also be involved. Our Bronte Street team listens to the timing, then examines the area, rather than starting with a product that may only dull the signal.
Please do not time it by drinking cold water over and over. A rough sense of how long the feeling lasts during normal life is plenty. Share that, along with whether it is getting worse, and the dentist can explain what is likely going on, recommend appropriate care, and say what should prompt a quicker call.

Think about the place, the trigger, and above all the duration. Report it honestly, without minimizing it or trying to name the condition.

When discomfort lasts well beyond the trigger, disrupts sleep, or begins by itself, call rather than wait for a routine visit. This pattern may need a sooner appointment and different testing, and a desensitizing paste is not the answer to it.
Treatment, whitening, a new toothpaste or rinse, an injury, or a change in bite can all be relevant. Mention the timing, but expect the dentist to examine the tooth rather than assume the recent event explains it.
Call promptly about swelling, a broken tooth, strong pain on biting, night pain, or symptoms that are rapidly getting worse. If a routine checkup is already on the calendar, tell us about the new symptoms so we can decide whether you should come in earlier.
A short, sharp reaction often relates to dentin that has lost some of its protective covering. Longer-lasting or spontaneous pain can point toward other problems that need different care. Because the sensations overlap, the examination is essential. Afterward, care may be a home product, a professional application, or treatment directed at a particular tooth.
Relief is not guaranteed to be immediate or permanent, whatever the approach. Ask what the plan is designed to change, how to follow it, and when it will be reviewed. You should also leave knowing exactly which changes mean calling right away.

Describing duration and night pain when you call helps the team decide whether you need to be seen soon. Clear information on the phone can save you from waiting too long or making an unnecessary extra trip.
If the examination finds decay, a damaged restoration, or another concern, that can be addressed directly instead of just easing the feeling. Ask how each recommendation relates to a specific finding.
When an area hurts, brushing it often stops. Mention where cleaning has become difficult so your approach and brush can be reviewed, keeping daily care manageable while the cause is sorted out.
The tests used depend on what the dentist finds. If you are worried something will set the tooth off, say so, and the step will be explained before it begins.
Explain how long each episode lasts, whether it wakes you, when it first began, and what sets it off. Mention recent treatment. A general area is fine if you cannot point to a single tooth.
The dentist checks the teeth, restorations, and gums involved. Specific tests or X-rays may be suggested to identify the source. Ask what each test is meant to show, and let the clinician know if you need a break.
You will learn what has been found and what remains uncertain. A conservative plan, if appropriate, comes with clear directions and a review date. If treatment is needed, ask about the choices, their limitations, and how soon it should happen.
Confirm home care, any treatment provided, and when to report progress. Ask which symptoms, such as night pain or swelling, mean calling right away. A product trial should be short and reviewed, never stretched out while symptoms worsen.
Follow the guidance for your own diagnosis and treatment. Care after a restoration is different from care during a desensitizing toothpaste trial.
Testing the tooth with ice or cold water to see how long it lasts keeps aggravating it. Brush with a soft brush and light pressure, using the method shown. Tell us if the area is still too uncomfortable to clean.
A desensitizing product may need regular use before its benefit is clear. Follow the directions, without combining treatments or increasing how often you use them. Ask about whitening if it seems to be making things worse.
Note roughly how long episodes last and whether they are becoming shorter or longer. You do not need to provoke them. Call if pain grows, starts happening without a trigger, begins waking you, or does not ease as expected.
Ask about duration, triggers, products, and how progress will be reviewed. Sensitivity covers a range of problems with different levels of urgency.
Call our Bronte Street practice to describe what is happening, especially how long the discomfort lasts and whether it wakes you. We will help arrange an assessment and tell you how soon you should come in.
Care follows the diagnosis. Lingering, spontaneous, or night-time pain, and any swelling, should be reported promptly rather than handled with products.
