Thanks for putting up your question on Just Answer.
It is not advisable to pull any tooth by oneself..As this tooth may appear to be loose but it is still attached to periodontal ligament down underneath.
The looseness of the tooth is caused by the swelling of the ligament that surrounds the root of the tooth. (The ligament is like a very sheer sock. The inside of the sock is attached to the root of the tooth, and the outside of the sock is attached to the bone). You can see that the length of the roots that are embedded in the bone is very great, and even if the tooth feels a bit wobbly, it is not likely to pull out of the bone, even if you give a great & fast movement to it.
If she tries to do so,there are chances that he might still leave some part behind and any attempt made to pull it can injure the soft tissue attachments thereby causing more pain and bleeding. The top is more likely to break off leaving the roots still in place & you will have seek a dentists assisatance to pull them out surgically for you. Finally, if you attempt to remove the tooth and fail in the attempt, the infection that has caused all the pain is likely to spread and cause a massive problem.
I will still advise you to seek a professionals help for her. If there is any urgent need and the pain or discomfort increases, you can call an emergency dentist for help. Look in the web yellow pages for emergency dental care.
