Yearly dental visits are a part of good dental hygiene because the dentist will check for cavities, fix them, clean your teeth very thoroughly (or whitening treatment), and check the progress and movement of your teeth. They can also recommend when dental surgery is necessary, for instance, if you have extra teeth that can be removed or when your wisdom teeth are coming in. Hope this helps! :)
        
                    
             
        
        
        
Rhinitis is an allergic condition characterized by inflammation in the mucus membrane lining of the nose. The anti-histamine nasal sprays controls the symptoms of allergy but it has rebound effect which means that though the sprays works well in controlling the disease, it still causes inflammation and damage to the mucus membrane lining of the nose that may lead to nausea and bleeding of nose.
