Hello, can teeth affect nighttime sleep directly? I've always had a routine of going to bed at 7-7:30 PM and waking up at 7 AM, only waking up for food. But on the third day, we have a cough all night long. The doctor said it could be the teeth because there are clear phlegm, wakes up at 1 AM and plays until 3 then at 5 and again plays. During the day, he cries capriciously and restless, also doesn't sleep properly for 30-40 minutes three times roughly.
