Eruption Cyst in Baby Teeth: Causes, Treatment & Prevention

Eruption Cyst in Babies (Teething) – Causes and Treatment

While teething may be challenging for some infants and their parents, it is a breeze for others. When it comes to your baby’s first tooth, you’re sure to notice several of the common symptoms. Continue reading to learn more about eruption cysts in newborns (teething) – their causes and treatment.

What Is an Eruption Cyst? 

A teething baby’s eruption cyst is a congenital eruption cyst or a hematoma cyst, depending on the kind of fluid that fills it. Both terms relate to the same thing: a teething infant’s eruption cyst. While a baby is still developing, their gums can become swollen and sensitive. At times, fluid-filled sacs and bubbles may be encountered. When a tooth erupts, it may develop on top of the gums or just below the gum surface. A process termed emergence. No treatment is necessary as long as the cyst has a fresh pearly white emerging from it.

What Causes an Eruption Cyst in a Newborn? 

At first glance, eruption cysts may seem to form spontaneously. If fluid (which may contain blood) accumulates around a tooth that is about to burst through the gum line, an eruption cyst may occur. Uncover the eruption cyst’s sign and its related causes.

  • Cavities in children may be caused by various circumstances, including inheritance, trauma, or a lack of room for the tooth to grow into.
  • When the dental follicle separates from the crown of an erupting tooth, a fluid-filled eruption cyst occurs, often found in children. When blood is present in the fluid, it is referred to as an “eruptive hematoma” (due to cyst destruction).
  • Since these cysts are associated with tooth emergence, they are more likely to develop during a person’s first two decades of life. Eruptive cysts may occur at any age, although the average age is seven years. 

What Are the Symptoms of an Eruption Cyst? 

Eruption cysts are, to put it mildly, unsightly and uncomfortable. Fortunately, the majority of eruption cysts will spontaneously rupture, producing little pain or discomfort. The following are typical eruption cysts signs and symptoms:

  • A bluish-purple or reddish-brown lesion, bump or bruise that occurs over a developing tooth.
  • It is conceivable that your kid has an eruption cyst, which shows on their gums as a little blue, yellow, white-tinged, or clear dome or bubble.
  • This soft tissue sore will form just above the growing tooth and may seem like a spongy, balloon-like protrusion along the gum line. 
  • Additionally, a slight degree of edema, discomfort, or redness may be present in the area around the eruption cyst.
  • The majority of eruption cysts have a diameter of less than half an inch, either one eruption cyst at a time or many at the same time.
  • On rare occasions, a trace of blood is seen in the fluid trapped within the eruption cyst. When this happens, the liquid’s color may change to pink, red, or purple.

What Are the Possible Risk Factors for Eruption Cysts? 

In the case of eruption cysts in infants, there is yet no known cause. However, studies have shown that the factors listed may increase the likelihood of babies developing eruption cysts:

  • Dental infection as well as early tooth decay
  • There is less space in the jaws for the tooth to erupt as a result.

How Eruption Cyst Is Treated? 

How Eruption Cyst Is Treated?

In the majority of cases, your kid will not need treatment for an eruption cyst. They usually disappear on their own when the tooth develops and pushes — or pops — harmlessly through the gap as it grows.

In certain situations, a tooth that is sluggish to develop or that is impacted (stuck) might produce a delayed eruption. If this occurs, your child’s pediatrician or pediatric dentist will attentively monitor the situation for many weeks to several months. On an X-ray, if fluid from an erupted cyst is present beneath the gums, a black shadow around the new tooth will be seen newly formed tooth.

In rare cases, it may be essential to consult with your doctor or a pediatric dentist if the eruption cyst interferes with the tooth’s natural growth. Thick or fibrous tissue must be removed from the tooth to aid in the normal development of the tooth. An alternative treatment method is known as ‘unroofing, and it comprises opening the top of the eruption cyst to release the tooth from its capsule. On the other hand, surgical treatment of eruption cysts in newborn babies is unusual.

How to Prevent Eruption Cysts? 

Eruption Cysts are seldom seen close to live teeth. There are a handful of preventive measures that you can take as a parent for your baby’s gums:

  • If the neurons in a tooth die owing to infection or damage, ta dentist should treat the tooth to prevent it from becoming a source of disease in the future. If this is successful, there should be no cyst growth in the tissues around the tooth’s root (or an abscess). The importance of seeing the dentist can’t be overstated.
  • Now and again, your child’s dentist may express concern that they may be suffering from a buried tooth. In such cases, 3D i-CAT computer scanning is recommended to assess three dimensions of the tooth location and health. 
  • This may help discover cysts while still small or prevent cyst formation by removing the potential starting element that might lead to cyst development.

When Should I Take My Baby to the Dentist? 

You should begin taking your infant to the dentist by the time they are one year old. The dentist will use an X-ray to look for cavities between the teeth ages four and six. Between the ages of six and twelve, when baby teeth become permanent, prevention is essential.

When your child’s dentist recommends a sealant between the ages of 7 and 9, it’s a thin covering of plastic resin that attaches to the teeth’s biting surfaces. If a molar is inflamed, it is more likely to need treatment, especially with Eruption Cysts. Sealing the crevices and ridges of teeth prevents germs from entering. The dentist may also do an orthodontic examination on your kid around the age of seven.

Your kid can acquire ‘eruption cysts’ during teething. These are tiny, harmless bubbles that emerge on the gums and vanish after a brief time. Infants and early children are less prone to have this illness than adults, but it becomes more prevalent when children develop adult teeth and begin chewing solid meals. Generally, eruption cysts resolve on their own and do not need additional medical care. Make an appointment with your child’s doctor immediately if the eruption cyst persists, bleeds, or seems to be infectious.


1. How Common are Eruption Cysts in Infants? 

Infants seldom have eruption cysts. Indeed, they are most prevalent in youngsters between 6 and 9, when their first adult molars grow. In older children under the age of 10, eruptive cysts are possible.

2. How Long Do Eruption Cysts Last? 

In most instances, an eruption cyst will disappear within a few days or weeks, as soon as the tooth emerges from under the gum line. The eruption cyst may linger for up to 4 months if the tooth develops slowly or is damaged in certain circumstances.

3. Are Eruption Cysts Painful? 

While an eruption cyst may sound unpleasant — and in infants, it may cause sore gums — it is usually not painful. Your child may have an eruption cyst, which manifests as small blue, yellow, white-tinged, or colorless domes or bubbles on their gum.

4. How Does an Eruption Cyst Look? 

When the fluids in the sac are coupled with blood, an eruption cyst is frequently bluish-purple but might seem reddish-brown when the fluids in the sac are combined with blood. It typically shows as a translucent dome of soft tissue surrounding a growing tooth. However, it can also take the form of a lesion or bruising.

5. Do Eruption Cysts Bleed? 

These cysts are harmless and form on the tooth’s mucosa shortly before it emerges. If the tooth is sore, bleeding, or contagious, surgery to expose it and drain any remaining fluids may be necessary.
