Although thumb sucking is a normal habit it causes serious teeth problems if it continues long after the eruption of permanent teeth. Prolonged finger sucking can create crowded, crooked teeth and bite problems. You may also develop speech problems or problems with swallowing properly. Protrusion and displacement of front teeth are usual results of thumb sucking. This can affect your facial appearance and cause further emotional problems. You can follow few steps to avoid the habit :Ask your family member to carefully remove your fingers from mouth during sleep Dont be in anxiety or fear. If you have any emotional problems, or under stress, and you need comforting, you may need to resolve those issues first before successfully stopping the habit. Use a finger sucking guard. - your dentist might suggest the use of special devices to stop thumb sucking, called finger guards. A finger or thumb guard is a device with a plastic cover of the thumb that is attached to wrist. . Treatment with thumb guards usually lasts four weeks and helps to stop thumb sucking successfully. I hope this helps, take care
