My 6year old daughter isn't eating right lately, she says it's because she feels like something is between her teeth, can you tell me what this could be?

Tooth pain: It would be impossible to tell you what may be between her teeth. However, she must be feeling something. Try flossing between her teeth and see if you pull anything out. Sometimes an infection can feel like something is wedged between the teeth due to inflammation. It's best to schedule a dental visit to evaluate.

Possibly decay : Decay between the primary (baby) molars is the most common cavity area for children.

Not without exam: An examination and possibly x-rays will be required to see between your child's teeth. It may be infection a9cavities or gum disease), food impaction, or just eruption of her 6 year permanent molars. Please have her exam lined by her General Dentist or specialist Pediatric Dentist as soon as possible to help her feel better.
