Many complications are involved in these procedures such as teeth can revert back to the previous position. In such cases retainers are used to keep them placed to the designated area. Again, Orthodontics decides which retainer is suitable. Individuals who refuse to accept the retainers can use the option of pre-finishers which are rubber appliances and aimed to fix the gap between the teeth. Major complication after the placement of braces is accumulation of plaque in the dental arcade and the places around braces. Only, detailed and regular cleaning and flossing can help in this regard. Metal braces don’t suit to some individuals because of the sensitivities and in them it can lead to allergic reaction. Non allergic alternative metals can be tried in such individuals. Tongue may hurt and lingual ulcers may develop if proper hygiene is not considered. Braces are not delicate but they also can’t bear strong traumatic events so in case of any sport events or any physical activities guards should be used to save your teeth from direct trauma.
