hello,
as per the description given by you,its not clear that whether the upper front teeth is milk teeth or newly erupted permanent teeth?

if it is milk teeth,you should get it removed as soon as possible.
if it is permanent teeth,get an x-ray of the tooth to rule out any periapical infection underlying.the tooth has to be restored or root canal treated.
maintain good oral hygiene.
brush your teeth regularly.

Hello there,
Permanent teeth start erupting at the age of 6 years and onwards,shark teeth or serreted teeth is the feature of milk teeth. as your daughter is 7 year old her permanent teeth will replace the milk ones. visit a dentist for confirmation, x ray examination will show the underlying permanent tooth buds accordingly go for treatment removal of teeth or to save the teeth. cleaning of gums and a course of medication will cure the swelling n redness of gums, take care.

Hello & welcome
as age of your daughter is of 7 years this is a mixed dentition age period.
go for a complete dental check up for her because every permanent teeth has a time of eruption, & they come at the place of milk tooth.
as far as swollen gums are considered that may be due to teeth problem, maintain a proper oral hygiene, & massage her gums regularly.
thanks & take care

Hi,

Thanks for asking the query,

According to your clinical symptoms i suspect that there is erruption of permanent tooth and exfoliation of the milk tooth due to which you are having the above symptoms.
I would suggest you to visit the Dentist and get the checkup done, take an x-ray of the tooth which will show the underlying permanent tooth buds or accordingly you can go for restoration or extraction of the tooth.
Go for complete mouth scaling and polishing
Maintain a good oral hygiene.

Hope this helps out.

Regards...
