Does toothpaste help cold sores?

posted byKore ProductsAugust 17, 2021

When you have a cold sore, you want to take immediate action.

You can also try home treatments for cold sores suggested by friends, family, or health websites, but these may not be clinically verified.

Some treatments only temporarily relieve symptoms, while other treatments may exacerbate cold sores.

A fast Google search revealed that toothpaste is a simple home cure for cold sores.

But is this medication safe and effective? Let’s see.

In this article, we will discuss the following things:

What causes cold sores?

The herpes simplex virus produces cold sores. There are two forms of the herpes simplex virus. (HSV-1) herpes simplex virus type 1 generally initiates cold sores, and (HSV-2) herpes simplex virus type 2 initiates typically genital herpes.

The two viral forms of cold sores are similar in appearance. HSV-1 can initiate genital pain, and HSV-2 can also produce cold sore.

Cold sores are contagious, but they can spread even if they are not visible.

By contacting someone infected with the herpes simplex virus, you may be infected with the herpes simplex virus.

It can be achieved by kissing, sharing food, or sharing cosmetics.

Oral sex can spread colds and genital herpes.

What are the symptoms and stages of healing?

Fever blisters normally pass-through multiple stages:

  • Stage 1: Many people experience itching, tingling, or burning around the lips for about a day before small, hard, painful wounds and blisters appear.
  • Stage 2: The blisters filled with small liquids usually open along the edges where the outer edges of the lips meet the facial skin. Cold sores can also arise around the nose and on the cheeks.
  • Stage 3: Small blisters may combine and rupture, leaving a thin open sore, fluid oozing, and becoming crusted. Cold sores normally scab in 4 days and heal totally within 8-10 days.

HSV-1 is the cause of cold sores. Unluckily, once you are infected with them, you will find sores on your lips.

Relapses usually occur in the same place and are often not as severe as the first eruption.

Other problems may also accompany the blisters symptoms caused by the initial fever, such as:

  • Fever
  • Headache
  • Nausea
  • Vomiting
  • Painful swelling
  • Open sores in the mouth
  • Sore throat

Does toothpaste treat cold sores?

This home solution is believed to produce the best results when toothpaste is applied to cold sores that have not until now fully manifested.

Fundamentally, if you feel that you have cold sores and you feel itchy or even tingling on the part of your face in the early stages of a cold sore, it is recommended to apply toothpaste.

Consequently, this method is used to prevent herpes from blooming into the vicious, ugly, and painful.

You may think that you need toothpaste to ensure that this method is effective, but this is not the case.

All you need is a white non-gel toothpaste that can be easily found anywhere.

You may already have this type of toothpaste.

When you feel that your cold sores are ready to grow, apply a thin layer of whitening toothpaste to this particular area. It is only used as topical care, not as a lotion.

For best outcomes, apply toothpaste before going to bed and rinse with warm water when you wake up in the morning.

If you want to use this technique throughout the day, you can.

To keep your toothpaste fresh, apply it every few hours throughout the day.

Well, if you are looking for a way to get rid of officially appearing cold sores, you can even now use this technique.

You can use toothpaste on the blisters and let them dry overnight.

Many people believe that whitening toothpaste can prevent not only the appearance of these blisters but also lessen the size of the blisters and ultimately help them disappear faster than normal.

Actual results of using toothpaste

There is no evidence that this method is effective, so it isn't easy to say.

If you limit yourself to people who have already tried this technique (many people), the results will be mixed even if it seems very positive.

When they feel that cold sores are about to come, some people say it is their home remedy, while others say it doesn't work at all.

It is difficult to draw a definitive conclusion because there are no actual statistics or evidence to support it.

Since everyone has different skin types, the results will always be different.

In other words, this technique may be suitable for some people but not for others.

Natural remedies for cold sores

Following few natural remedies may treat cold sores:

  • Lemon juice has an antibacterial effect and is suitable for cold sores.
  • Teabags can be used as a cold compress to cool the redness around the cold sore. Though, it is necessary to fight against complete infection.
  • Denatured alcohol and witch hazel are astringents that help dry sores.
  • Using ice cubes for cold sores is a simple home cure for cold sores that can relieve momentary pain and lessen the redness and inflammation of cold sores.
  • It cannot thrive because salt can help change the environment around the virus. Cold sores can be dried, but they can also cause pain to the skin.


Cold sores are blisters caused by HSV and generally develop around the mouth.

Destroying cold sores can exacerbate the condition by releasing infectious liquid from the inside of the blisters.

This fluid can cause more cold herpes, infections, and scars.

Cold sores generally resolve on their own without treatment, but toothpaste can help relieve symptoms.
