Fine But 1st think is third molar surgey is needed.
There's nothing worse than making well something that you should not make.
No hay nada peor que hacer bien lo que no hay que hacer.

Prevention? Let the third molar (wisdom teeth) in peace. At least 2/3 are unnecessary extracted.
10 million third molars (wisdom teeth) are extracted in the USA per year.
¿Prevención? Dejad el 3r molar (muela del juicio) en paz. Al menos 2/3 extirpados sin necesidad.
Se extirpan al año en EEUU unos 10 millones de 3r molar.
