Eruption cysts: how to evaluate a bubble on the gum of the child | Dentistry study Stere

During the eruption of a tooth can appear a bubble on the gum, sometimes transparent or bluish. Seeing her doesn't mean knowing what she is.

Among the possible explanations is the eruption cyst, a superficial collection associated with the tooth that is emerging.

The evaluation is mainly used to distinguish cases from those with pain, infection or other elements that require attention.

What is eruption cyst

It is a collection of liquid in soft tissues over the crown of a tooth in eruption. When in the liquid is present blood can be called eruption hematoma. The color does not measure gravity alone.


 

The elements to be observed without manipulating

Report with the tooth

The position above an element that is emerging is a useful data, but must be verified by the dentist.

Content of tumeface

A blood component can explain the bluish or dark color. It's not the pus test alone.

Small local trauma

Contact with the area can affect its appearance. You don't have to keep pressing for consistency.

Evolution of eruption

The appearance of the tooth and the changes of the bubble should be read together, considering the development of the teething.

When the picture should be reassessed soon

Growing pain, secretion, swelling that extends or difficulty eating deserve a quick contact. Fever or malaise should not be settled as simple teething; breathing or deglutition compromised require urgent assistance.


 

Because not all bubbles are equal

A mucocele is about a salivary collection, often on the lip. An eruption cyst is connected to the emerging crown. Other performances have different origins: home, history and visit count more than a photographic resemblance.

How to control

The dentist observes injury, identifies the tooth concerned and collects information about duration, pain and nutrition. Any diagnostic images are chosen for a precise doubt; not every bubble automatically requires an X-ray.


 

Observation and possible intervention

Accompanying the eruption

In many cases the tooth emerges through the collection without the need for a procedure.

Define control

If you choose to observe, it is useful to know what changes to report and when to return.

Manage a problematic injury

If it persists or is infected, the professional can assess an opening of the surface tissue under controlled conditions.

Reconsider diagnosis

An atypical trend requires a new evaluation, instead of repeating attempts at domestic treatment.

What to avoid waiting

Do not wash, affect or squeeze the swelling and do not apply irritating substances. Keep a delicate cleaning compatible with the comfort of the child and ask for directions for any difficulties in meals.
