Baby is currently teething at top where her teeth is coming in is filled with pus all around and on her gums?

Needs to be seen: If this is truly pus, she needs to be seen by her doc or dentist.There are a number of germs that can cause gum disease in kids and this should be evaluated and treated.

Not pus: This is probably a normal tooth bud. Keep an eye on this.

Pus: Doubtful, but not unheard of. I would suggest that you make an appointment with a Pedodontist, a Pediatric Dental Specialist, who can examine your child and make recommendations. No, it's not too soon. Go now.

Unusual: Its unusual for newly erupting teeth to have infections. Possibly the eruption cyst before the tooth has broken through the surface. If it is an infections you should take them to a pediatric dentist immediately

Pus?: May be eruption cyst and not pus. Take your child to a Pediatric Dentist (Pedodontist) asap for evaluation as if it's truly an infection (doubtful) she needs proper and prompt attention.

Pus is not normal: Most two years olds are no longer teething on top front teeth. If this is the area you are concerned about it may be Early Childhood Caries and not teething. If you are talking about upper back teeth, they could be teething, but PUS is NOT normal with teething. Regardless this child needs to be seen by a Pediatric Dentist as soon as possible.

Not likely: to be pus, but will look white. Cold teething ring often helps. See a dentist for proper diagnosis.
