Should I be worried if my upper front tooth had bled once?

Hi,

Welcome to icliniq.com.

I have gone through your question.

I can understand your concern about your loose tooth. Your tooth number specifies the upper left lateral incisor, which has the smallest root among the upper teeth and is vulnerable to any difficult circumstances. I suggest you get an IOPA (intraoral periapical radiograph) done. The probable causes are trauma and periodontitis. If the tooth root is fractured, you may need to remove it. If the whole tooth is mobile, you can get it splinted by a dentist. It will heal and become firm. In the meantime, do not take hard and solid foods like bread, apples, carrots, etc.

I hope this helps.
