Everything You Need to Know About Teething Rash

What is that weird rash on your baby’s chin? Are you wondering how it got there?

It might be a common problem for babies — a teething rash.

What is this rash? Is it a sign of another illness, and is there anything you can do about it? To help you and your baby through these tough times, we gathered everything you need to know about teething rash.

Let’s look at the causes, as well as tricks to make this rash vanish.


What Is Teething Rash?

Teething rash is a skin rash characterized by red patches of skin and small, raised bumps. Your baby’s skin will likely look chapped and dry. The appearance of teething rash is often compared to eczema.

It is important to look for other symptoms of teething alongside the developing rash. Properly identifying the source of a rash allows you to treat it correctly and quickly.

Here are a few common signs of teething to watch out for:

  • A visible, erupting tooth from your baby’s gum line.
  • Swollen, inflamed gums.
  • Ear tugging — the nerves in the gums may give your baby an odd sensation in the ears.
  • Excessive biting or sucking on food and objects.

Teething rash most often appears around a baby’s lips and cheeks. However, don’t be surprised if you find evidence of teething rash on your baby’s chest, hands, and feet.

What Causes Teething Rash?

The main culprit behind those sensitive red bumps on your baby may surprise you. It’s drool!

Saliva contains multiple enzymes to aid in digestion (source). As we eat, these enzymes begin to break down the food so our bodies have an easier time digesting it. As your baby grows during the first year, the salivary glands begin to develop.

Because your baby doesn’t have the full capability and know-how to swallow all of the saliva produced, it most often flows out of the mouth as drool.

When your baby starts teething, these already growing glands are kicked into overdrive. As the teeth erupt from the gum line, your baby’s biological reflex to salivate is stimulated (source).

The enzymes which help your baby digest solid foods then come into contact with the skin, causing irritation and, you guessed it, a rash.

Teething Rash on the Body?

But wait! If teething rash is caused by drool, why does the rash appear on other areas of the body?

Well, there are two main causes.

  • First, as you have likely discovered, your baby can make all sorts of messes you never imagined. The hands and feet can easily be placed in their mouths where an abundance of drool is present. Drool can also dribble down into the folds of your baby’s neck and onto the chest.
  • Second, your baby will likely react to teething rash by scratching and rubbing their skin. Not only does this aggravate the rash, but it transfers drool to other parts of the body.

If a rash appears on the body and your baby is not showing major signs of teething, it may not be teething rash at all. If you are unable to determine what is causing your baby’s rash all over the body, contact your doctor.

How Can I Prevent Teething Rash?

Are you hoping to prevent teething rash entirely? A little bit of knowledge is all you need.

Here are a few helpful tips to avoid adding this extra bit of stress on you and your baby during the teething process:

1. Keep the Drool at Bay

If you want to prevent teething rash, do all you can to keep your baby’s skin free of drool. Keep a soft cloth handy and dab the drool away often. Avoid rubbing and wiping because these harsh motions can aggravate the skin further.

If your baby seems to drool excessively, have them wear a bib to protect their neck and chest. There are special bibs made especially for drool control. Some feature silicone and pockets to catch liquid while others are soft and super absorbent.

Pacifiers can increase your baby’s need to drool. When they use a pacifier, they are using their mouth muscles more heavily, stimulating the need to drool. Pacifiers can also hinder your baby’s ability to learn to swallow at a consistent rate (source).

Pacifiers also trap drool between the pacifier and the skin, causing the rash to be worse around the mouth.

2. Take Care of Your Baby’s Skin

Teething rash is exacerbated by overly dry skin, which can occur when you are constantly wiping your baby’s mouth. Dab gently and make sure to keep your baby’s skin clean and lightly moisturized. Use a baby-safe lotion or soothing oil.

Be careful though! Too much moisture or product can also irritate your baby’s skin. You should use just enough to prevent chapping.

It’s also important to pick other products, such as body wash and shampoo, specifically formulated for your baby’s sensitive skin.

3. Change Your Baby’s Clothes Often

If your baby is drooling enough that it’s soaking through their clothes, make sure to change them often. The drool on clothing plus the friction of the fabric against the skin can equal a nasty teething rash on your baby’s chest and tummy.

You will also want to make sure you are using a clothes detergent that is safe for your baby’s skin. Detergents with heavy fragrance can be especially irritating.

Launder any clothing or bedding items that may be drooled on regularly. This especially includes any sheets or blankets.

How To Treat Teething Rash

If your baby already has teething rash, don’t fear. Teething rash can be easily treated and is not considered an indicator of any illness other than teething.

Follow these five simple steps to treat teething rash as soon as it appears.

1. Dismiss the Drool

Just as is it important to remove drool to prevent teething rash, keeping your baby’s hurting skin free of drool is the most important step to take in treating it.

Because your baby’s skin is already inflamed, be extra gentle in dabbing the drool away. If the weather permits, keep your baby in limited clothing to avoid friction. Or, pick clothes made of soft, smooth fabrics.

2. Protect the Hands

To keep your baby from scratching and rubbing at their rash, have them wear mittens or clothing that covers their hands. Also, make sure their nails are cut short.

If your baby is having a hard time keeping their hands away, try distracting them with sensory toys appropriate for their age. Toys that glow, make noise, or squish are especially fun.

3. Soothe and Moisturize

Prevent the rash from growing worse by carefully washing your baby with a gentle cleanser and applying a light moisturizer. All should be specifically formulated for babies and be free of scents and perfumes.

Another option is to apply a small layer of petroleum jelly to your baby’s skin. It helps create a barrier between the rash and the drool.

4. Cold and Chewy

Give your baby something cold and chewy to gnaw on. Not only will it make their gums feel better, but the cold will help take away the painful sting that comes with teething rash.

The most common items are chilled pacifiers, teething rings, or washcloths. Cold fruit, nearly frozen applesauce, and popsicles are also great choices. Make sure to monitor your little one to ensure an item is not too cold.

5. Baby Gum Massage

Give your baby a gum massage to relieve the pain of teething. Gently stimulating the gums increases necessary blood flow, which will help in the healing process.

How Long Will Teething Rash Last?

With quick and constant treatment, teething rash should clear up within a few days to a few weeks. However, every case is different and it is important to monitor your baby’s symptoms and progress. We suggest taking pictures on your phone of the rash to help track the visible symptoms and improvement.

If the rash does not visibly improve throughout a week with steady treatment, consider talking to your pediatrician about other measures you can take.

How Long Does Teething Itself Last?

You have just gotten through a nasty round of teething rash. Now, your baby has a bright little tooth and all seems well. However, before you know it, the process starts all over again.

There is no exact timeline for teething. It is important to remember teething specifically refers to the process of a tooth erupting from the gums and does not include the growth of the tooth after it has erupted.

Throughout two years, your baby will grow 20 baby teeth (source). Many teeth can erupt at once. Even though your child will still have teeth growing as they enter their toddler years, they will have learned to control their drooling reflexes and teething rash should be a thing of the past.

When Teething Rash Leads to Infection

In rare cases, teething rashes can become infected. You can tell a rash is infected if it becomes severely cracked, weepy, or if you detect other fluids, such as pus or blood.

If you suspect an area of teething rash is infected, contact your doctor right away. They will be able to suggest any medications needed and further steps to protect and heal your baby’s skin.

When treated promptly, teething rash does not have to ruin you and your baby’s day. All you need is a bit of information and some basic supplies.
