Hi. The X- rays are not attached.
Still Extraction of the tooth is not the last option. Root canal is also done but depends on how the tooth condition is.
Yes missing tooth will impact speech, eating, esthetics and so on many problems. But based on which tooth we are talking about there are many other options even after extraction which will help prevent all those concerns of yours.
Next Steps
Post pics and X-ray for clear guidance. Visit a Pedodontist for clear idea.
Health Tips
Milk tooth is always backed up by a permanent tooth, so don't worry. But still which tooth, its position, function has its importance as milk tooth is not a dummy tooth. Take care.
