Cold sore treatment in Herriman

A cold sore can sting, look sore and show up at the worst time. You cannot cure the virus behind it, but you can often help a sore heal faster and come back less often.

What is a cold sore?

A cold sore is a small, painful blister on or around the lips. It is caused by a common virus that stays in the body after the first infection. Sores often heal on their own in one to two weeks, but they can come back.

  • Often starts with tingling or burning before a blister shows
  • Spreads easily through close contact while a sore is present
  • Stress, illness and sun can bring on a flare-up

When to ask your dentist about a cold sore

Most cold sores clear up with simple home care. It is a good idea to talk with your dentist if:

  • You get cold sores often
  • A sore is very painful or makes it hard to eat
  • A sore has not healed after two weeks
  • You have a dental visit coming up while a sore is active

Not every sore around the mouth is a cold sore. Canker sores form inside the mouth and are not contagious. A sore that will not heal should always be checked, which is part of an oral cancer screening at your regular visit. If you have a weak immune system, or a sore near your eye, check with your medical provider right away.

How your dentist can help

  1. A quick look. Your dentist checks the sore to confirm what it is and how far along it is.
  2. A care plan. Depending on how often you get sores, your dentist may suggest over-the-counter products or a prescription medicine to help sores heal sooner and flare up less.
  3. In-office care. For some patients, your dentist may offer a light-based laser treatment that can ease discomfort and help healing.

Treatment works best when it starts early, at the first tingle. If you know your triggers, ask your dentist how to be ready.

Cold sores and dental visits

An active sore can crack or spread during dental work. Let us know if you have one before your visit. We may move a cleaning or treatment to a later date.

Caring for a cold sore at home

  • Keep the area clean and avoid picking or touching the sore. Wash your hands if you do.
  • A cool, damp cloth can ease burning and swelling.
  • Do not share cups, utensils, towels or lip balm while a sore is present.
  • Skip kissing and close face contact until the sore is fully healed.
  • Use a lip balm with sunscreen if sun brings on your sores.
  • Rest, eat well and manage stress when you can, since being run-down can trigger a flare.

Cost and insurance

Your cost depends on the care you need and your dental plan. After your exam, we give you an estimate and go over what your insurance is likely to cover before any treatment starts. We work with most major dental plans and accept CareCredit.

FAQ

Questions about cold sore treatment

What causes cold sores?
A common virus causes them. It spreads through close contact, such as kissing or sharing a cup. After the first infection, the virus stays in the body and can wake up again because of stress, illness, hormones, sun or a skin injury.
Are cold sores contagious?
Yes, from the first tingle until the sore is fully healed. They can still spread at other times, though it is less likely.
How long does a cold sore last?
Most heal in one to two weeks without a scar. Starting treatment at the first sign may shorten that.
Can I keep cold sores from coming back?
You may not be able to stop every one, but knowing your triggers helps. Sun protection on your lips, rest and stress care can lower flare-ups. If you get them often, your dentist can talk with you about a plan.
