Tooth pain has a way of taking over your whole day. The real problem is rarely the pain itself, it's whatever's causing it, and that's exactly what we find and fix first.
Tooth pain has a way of taking over your whole day. The real problem is rarely the pain itself, it's whatever's causing it, and that's exactly what we find and fix first.

Dental pain usually comes from one of a handful of causes: a cavity that's reached the nerve, a cracked tooth, an infection at the root, gum disease, or a tooth that's simply too sensitive to hot and cold. The pain itself can feel similar across all of these, which is why figuring out the actual cause matters more than just numbing the ache.
Tooth pain rarely shows up out of nowhere. By the time you feel it, something underneath has usually been building for a while, a cavity working its way toward the nerve, an old filling starting to fail, or an infection quietly spreading at the root. Painkillers can dull it for a few hours, but they don’t touch whatever’s actually going on, and that gap is exactly where small problems turn into bigger ones.
That’s really the whole case for coming in quickly rather than waiting it out. A tooth that’s treated early is often a straightforward fix. The same tooth, left alone for a few more weeks, can turn into a root canal, or worse, a tooth that can’t be saved at all.

Often points to a cracked tooth, a loose filling, or a cavity that's reached a sensitive layer of the tooth. The pain usually comes and goes with pressure rather than staying constant.

If the discomfort fades within a few seconds, it's often just sensitivity from worn enamel or a receding gum line. If it lingers for a while after the hot or cold is gone, it can mean the nerve inside the tooth is inflamed or infected.

Often a sign of a deep cavity or an infection that's reached the nerve. This kind of pain tends not to let up on its own and is the one most likely to need prompt attention.

Usually means an infection, possibly an abscess, that's spread beyond the tooth into the surrounding gum or jaw. This combination is worth treating as urgent rather than waiting to see if it settles.

Can point to a cavity, a cracked tooth, or sometimes gum disease affecting the tissue around a specific tooth. Worth a proper look even if the pain is mild, since it tends not to resolve by itself.

Often a sign of deeper tooth decay or nerve irritation. Pain that becomes worse at night or keeps waking you up may indicate that the tooth needs prompt dental attention.
If any of these sound like what you’re dealing with, call us rather than waiting for a routine appointment slot.

Dr. Mathur asks what the pain feels like, when it started, and what sets it off, details that narrow down the likely cause before any examination even begins.

The tooth and surrounding area are checked, with an X-ray taken where needed to see what's happening below the surface, a cracked root, a deep cavity, or an infection, that isn't visible otherwise.

You'll be told plainly what's actually wrong, not just handed a prescription for painkillers and sent on your way.

Immediate relief comes first, numbing if needed and addressing anything urgent, followed by a clear plan for the treatment that actually resolves the cause, whether that's a filling, a root canal, or something else entirely.
Dr. Rajat Mathur combines clinical expertise, modern dental technology, and a patient-first approach to provide comprehensive dental care designed around your comfort, oral health, and long-term smile.

Dr. Rajat Mathur has been my family's go-to dentist for over 12 years, and I trust him completely. He's not only highly skilled and professional but also genuinely caring. He always explains the treatment options patiently, never recommends anything unnecessary, and makes every visit comfortable. Over the years, he's consistently provided excellent care, and that reliability is why I keep coming back. Finding a dentist you can trust for so long is rare, and I'm truly grateful to have found Dr. Mathur. Highly recommended!Posted on Google![]()

Hello everyone I started coming to Dr. Rajat Mathur 12 years back and it has been good journey and experience getting dental treatment from him. I was facing lot of problems in bite and then consulted few dentists but they were not able to diagnose the cause. Though, when I visited him, he properly checked the situation and a major issue of grinding of teeth was diagnosed by him. Since then getting the treatment from him and visiting the clinic when called or required. Overall, it has been a great experience getting the treatment from him with all positive vibes and slow chanting music in his clinic.Posted on Google![]()

Excellent Staff. Had a good experience with Serene Smiles
Rinse with warm salt water, take an over-the-counter painkiller if you're able to, and avoid very hot, cold, or hard food on that side. If there's visible swelling, a fever, or pain that's severe and unrelenting, call us rather than waiting, this can point to an infection that needs prompt attention.
No. Pain can come from something as simple as sensitivity or a small cavity that just needs a filling. A root canal is only needed once the infection or decay has reached the nerve inside the tooth, which is exactly what the examination is for, finding out which one you're actually dealing with.
This is a common sign of a crack in the tooth, a loose or failing filling, or decay that's reached a sensitive layer. It's worth getting checked even if the pain is mild and comes and goes, since this kind of pain tends to get worse rather than resolve on its own.
Yes, an impacted or partially erupted wisdom tooth is a common source of pain, especially toward the back of the jaw, often with some swelling. See our Wisdom Tooth Removal page for more on that specific cause.
Some mild sensitivity for a few days afterward is normal and usually settles on its own. Pain that's severe, getting worse rather than better, or still present after a week or so is worth having checked.
Same-day appointments are available for urgent pain. Call or WhatsApp us and we'll get you in as quickly as we can.
Yes. Advanced gum disease can cause pain, especially when chewing, as the tissue and bone supporting a tooth break down. See our Gum Diseases page for the fuller picture on that.
The pain may come and go, but whatever's causing it, a cavity, a crack, an infection, doesn't resolve on its own and tends to get worse with time. What might be a straightforward filling today can turn into a root canal, or in some cases a tooth that can't be saved, the longer it's left untreated.
