Some children are born with extra tissue called frenum under their tongue or upper lip. These are called tongue-ties and lip-ties and can cause difficulty with speech, breastfeeding, weight gain, and even dental decay.
If not treated during childhood, the adverse effects of tongue and lip-ties can follow children into adulthood. Headaches, neck and shoulder pain, sleep issues, and speech problems are all signs of untreated tongue and lip-ties.
