Tooth Pain Explained: Why It Hurts and What to Do

By Monarchy Media LLC on September 23, 2025 at 12:00 AM

A toothache can come on suddenly and feel overwhelming. Maybe it starts as a dull throb that gets worse when you bite down, or perhaps it jolts you awake at night with sharp, pulsing discomfort. Whatever the cause, tooth pain is your body’s way of saying something needs attention. At Hillside Dental Care, we understand how disruptive a toothache can be and how important it is to find both immediate relief and long-term solutions.

In this blog, we’ll focus on three of the most common questions people ask when tooth pain strikes.

What is the fastest way to stop a toothache at home?

When tooth pain catches you off guard, late at night or on a busy workday, you need quick relief. While a dentist visit is always the ultimate solution, there are steps you can take right away to calm the pain until your appointment.

Start by rinsing your mouth with warm salt water. This simple mix helps clean the area, ease inflammation, and may dislodge tiny food particles irritating the tooth. A cold compress on the outside of your cheek can also bring down swelling and numb throbbing pain. Hold it there for 15 to 20 minutes at a time and repeat as needed.

Over-the-counter oral numbing gels containing benzocaine can provide temporary relief by numbing the affected tooth and gums. Just be sure to follow the instructions carefully and avoid using them on children under two years old. If you have no numbing gel on hand, even gently flossing around the sore tooth can help remove trapped debris that’s causing pressure.

Another overlooked step is to keep your head slightly elevated when resting. Lying flat increases blood flow to the head and can intensify pain, so propping your head with pillows may reduce pressure around the sore tooth.

These methods can give hours of comfort, but they don’t fix what’s wrong inside the tooth. Whether it’s decay, a crack, or a hidden infection, only professional dental care can solve the problem for good.

What is the best painkiller for toothache?

Pain relief is often essential when you’re waiting to see a dentist. Choosing the right over-the-counter medication can make a big difference. Ibuprofen is frequently recommended because it tackles both pain and inflammation, which is crucial when swelling or pressure inside the tooth is contributing to discomfort. If you can’t take ibuprofen, acetaminophen is another effective option that reduces pain, though it doesn’t target inflammation in the same way.

Some people find that alternating ibuprofen and acetaminophen (taken at the correct dosages and intervals) provides stronger relief than using either on its own. Always follow the instructions on the packaging and check with your doctor or pharmacist if you have any medical conditions or take other medications.

Avoid placing aspirin directly on the tooth or gums, a common but harmful myth. Direct contact with aspirin can burn the tissue and lead to more irritation rather than relief.

Painkillers are only meant to buy you time until treatment, not to delay it. If tooth pain lasts more than a day or two or keeps coming back, it’s a sign of a deeper issue like infection, a cavity, or gum disease. These need to be treated at the source by your dentist to prevent serious complications like abscesses or tooth loss.

Can a toothache go away on its own?

Sometimes tooth pain fades, making it tempting to believe the problem has disappeared. Unfortunately, a vanishing toothache rarely means the tooth has healed. In many cases, it can mean the opposite. What feels like relief might simply be the quiet stage of a deeper issue.

If a cavity or infection damages the nerve inside the tooth badly enough, the nerve can die and stop sending pain signals. While that might bring a temporary sense of comfort, the infection can continue to spread silently through the root and surrounding tissues. Over time, this hidden infection can damage bone, affect neighboring teeth, and in rare cases spread to other parts of the body.

Other times, an abscess, a pocket of pus caused by infection, may drain on its own, which briefly lowers pressure and eases pain. But the source of infection remains and can refill or flare back up unexpectedly. Without professional treatment, the infection often returns stronger and more painful than before.

Even mild sensitivity can progress without warning. What starts as an occasional twinge when you sip something cold may deepen into throbbing pain as decay reaches the inner layers of the tooth. Once bacteria reach the pulp, only dental treatment such as a filling, crown, or root canal can stop the damage.

In rare situations, very minor irritation, such as gum inflammation from a piece of food lodged between teeth, can resolve if you improve your brushing and flossing routine. However, this is the exception, not the rule. If you’ve experienced anything beyond brief sensitivity, it’s safest to schedule a dental exam as soon as possible.

Leaving a toothache untreated can lead to:

  • Advanced decay and larger cavities that require more complex treatments.
  • Bone loss or gum damage that weakens the support of surrounding teeth.
  • Chronic infection or abscesses that can impact your overall health.
  • Tooth loss if the tooth becomes too damaged to save.

Early care almost always means simpler, less invasive treatment. A small cavity can often be resolved with a straightforward filling. Waiting until the pain forces you to act can mean a root canal, a crown, or even extraction.

If tooth pain appears and then fades, consider it a warning sign, not a green light to ignore the problem. A quick appointment at Hillside Dental Care can uncover the cause and protect your smile before a minor issue turns into something serious.

Take the Next Step Toward Relief

Tooth pain is a clear signal that something inside your mouth needs attention. Quick home remedies and painkillers can help you manage discomfort for a few hours, but they cannot remove decay or stop infection. The only way to protect your smile and health is to see a dentist who can diagnose and treat the cause.

Schedule an appointment with Hillside Dental Care today to end tooth pain and prevent future problems. Acting early means easier treatment, better results, and peace of mind.
