If you live in South Surrey or White Rock and a cold drink leaves one tooth aching long after the last sip, you're probably wondering whether it's something to watch or something to act on. This guide explains how to tell the difference, what a dentist looks for, and what to expect if you book a visit.
Two kinds of tooth sensitivity
Not every twinge means the same thing. Dentists generally separate sensitivity into two broad types:
| Everyday sensitivity | Pulp hyperemia | |
|---|---|---|
| How it feels | Quick, sharp twinge | Ache that lingers |
| How long it lasts | Fades within seconds | Continues after the cold or sweet is gone |
| Usual source | Exposed dentin from gum recession or worn enamel | Irritation inside the tooth's pulp |
| Pattern | Often several teeth | Often one tooth that stands out |
The pulp is the living core of the tooth, holding its nerves and blood vessels. In pulp hyperemia, extra blood flows into the pulp as it reacts to irritation. It is often an early stage, which is exactly why it is worth catching now.
What can irritate the pulp
Several everyday situations can leave the pulp inflamed:
- Deep decay reaching toward the inside of the tooth
- A recent filling or crown, while the tooth recovers
- A cracked tooth
- Grinding or clenching
- A sudden knock to the tooth
If your sensitivity began after recent dental work, mention it. It is useful information, and the tooth may simply need time and a follow-up check.
Signs it may be more than everyday sensitivity
- Pain from cold or sweets that lingers
- An ache that continues after the trigger is gone
- One tooth that clearly stands out
- Sensitivity after a recent filling or crown
Call promptly if the pain throbs, starts on its own, or keeps you up at night. Those are signs to be seen sooner rather than later.
What happens at the dental visit
Finding the cause comes first. A typical visit follows this order:
- Listening: we ask about your symptoms and when they happen.
- Examination: we look closely at the tooth and surrounding area.
- Testing: gentle cold testing and a low-dose digital X-ray help show what is going on.
- Treating the cause: this might mean sealing decay, protecting the tooth, or adjusting the bite.
- Follow-up: we check that the tooth has settled.
Caught early, an irritated pulp often calms down once the cause is found and treated, and the tooth stays healthy. If the pulp can't recover, a gentle root canal can still save your natural tooth. You can read more about the options on the Morgan Heights Dental treatments page.
Why waiting it out isn't ideal
It is tempting to hope a sore tooth will sort itself out. The concern is that irritation can progress. An irritated pulp is often reversible, but ignored, it can become an inflamed pulp called pulpitis, with more constant pain, and later a damaged nerve that needs a root canal. Acting early generally keeps treatment smaller.
If dental visits make you nervous
Feeling anxious is common and completely understandable. One reviewer with severe dental anxiety met with four dentists before choosing Dr. Farid Alenabi, describing him as thorough, patient, and understanding. If anxiety has kept you away, our family dentistry page is a gentle place to start learning what care looks like.

If one tooth just won't settle, a gentle look is a good next step. New patients are welcome, and booking takes only a moment.
