Dear ma'am,
The problem that you seem to be facing about your child's front teeth is a normal phenomenon that happens between the age of 5-7 years. The teeth that are shaking are the milk teeth and they will fall off when the teeth coming from behind are completely ready to come in the mouth (the normal age for them to come is between 6.5- 7.5 years).
Next Steps
Make a visit to the dentist for any other queries
Health Tips
Do not let your child pull out the shaking teeth before they fall out themselves.
