Hi, Adenoids are something similar to tonsills but are located behind your nose. So normally they are not visible from the mouth. They can be seen directly through the nose with the help of endoscope or with indirectly the help of X-Ray. As far as your symptoms are concerned and the images that you have uploaded it doesn't look like adenoids symptoms. Moreover your tonsills and throat also looks normal. Nasal congestion on getting up in the morning can be due to sleeping directly under cool breez of air. And dryness of mouth can be due to mouth breathing while in sleep. As a home remedy I will suggest you to try steam inhalation twice daily for few days. Don't worry it's nothing serious. However if your problem persists or you have any other query please do consult online.

Generally having an adenoid issue at this age is unlikely Need to be evaluated further

How do you know that it is an adenoid problem? If u r having adenoids, then nasal spray is more effective along with allergic medicines

The picture you have shown is of tonsils.. Adenoids are not seen at this age.. Congested dry nose and throat pain could be because of allergy
