My 3yrs old daughter fixing to have crowning for her cavities. my question is: would the crowning bother her and preventing her normal eating?

No: Crowning her baby teeth will not bother her or prevent normal eating. What is not normal is why does she needs this? It is not normal for a child of 3 to need crowns. Kids don't have to get this kind of decay without something being very wrong. Find out why this is happening.

No it won't : It will be just like an adult receiving crown. If this is her first dental experience , make sure the doctor is willing to be patient., since this experience will stay with her sometimes for the rest of her life. That's why we see adult who are very anxious with dental appointments.

No as long as she is: As long as the crowns did not interfere with he bite relationship.

No: If at age 3 the dentist is indicating crowning, then the problem was most likely that she had been put to bed many many times with a milk bottle. The milk resting on the teeth over a long period of time will destroy them. The crowns are to cover the damaged teeth to provide her a better eating since the destroyed teeth cannot function any longer.

Bigger issue is: I'm in full agreement with Dr. Klugman. The bigger concern is the future. Rampant caries could have many causes, especially high sugar content foods and liquids. Sleeping with a bottle other than water also causes this. Discuss her diet and this issue with a pedodontist and make a change so these bad habits do not destroy her permanent teeth as well. That would be a great gift to your daughter

Not normally!: If the decay in a primary or "baby" tooth is to extensive, often times a stainless steel crown is used to replace the decayed tooth structure once the dentist removed it. This allows the child to function normally and the space for the appropriate positions for the adult teeth are maintained. Always remember that the crowns maybe made of stainless steel, but you the parent must help cleanher teeth.

No: The large cavities that she has now will bother her and prevent her from eating. Restoring this badly decayed teeth with crowns will help solve this problem and make it so she is comfortable and can eat better. To prevent future cavities you need to brush her teeth twice daily and make sure she eats healthy foods (no fruit roll ups, soda, etc.).
