Teeth Whitening

On July 27, 2016

Teeth whitening is one of the most requested procedures done these days in the dental office because it is a simple and painless process and that gives an aesthetic benefit in only one hour.

We have to keep in mind the reasons why teeth start to turn darker. The first reason is age, because you start to lose the enamel layer and the dentin makes the tooth look more yellow; the second reason is the metal and/or composite restorations. With time, metal starts to pigment the rest of the tooth a greyish color and the composite when turning porous starts to pigment because of the drinks and food we eat. The third reason would be that the tooth has a root canal which devitalizes it and turns it grayish; and lastly the external agents like tobacco, coffee, wine and other tinted foods.

There are two types of teeth whitening, the interior and the exterior; the interior whitening is only done when a tooth has lost its pulp (root canal) turning grayish. The exterior whitening is a procedure that is done the most because of its aesthetic purpose, here we use a 40% hydrogen peroxide based gel which is applied to the surface of the teeth in 2 intervals of 20 minutes each.

It is important to know that the only side effect produced by a teeth whitening is dental sensitivity, which can be controlled by desensitizers.

The cares after doing the whitening will help the result last for more time, therefore the patient must be aware that his diet and habits will be what contributes to this result.

Porcelain Crowns

On June 25, 2016

  I prefer porcelain crowns over the metal porcelain crowns because they don’t stain the tooth and the metal doesn’t start to show; the translucent ones looks more natural than the metal ones because these always look grayer.

  I’ve been offering porcelain crowns since I finished university. The last metal porcelain crown that I did was while I was still a student.

  These types of crowns are nothing new, the truth is they have been around for more than 20 years.  The reason that they haven’t offered them to you might be that the dentist may not be up to date on the modern materials that exist. In the past it wasn’t possible to offer porcelain crowns without the aid of metal because they would fracture, but because of technology and the advances of dentistry in computers, now they can make porcelain crowns this way. Besides, there are patients that prefer to avoid contact with metals because of health reasons,  therefore these types of crowns are a better option for them.

  You may come to think that changing your metal porcelain crowns for zirconia (which is a type of porcelain), have to be done in a few appointments, but really it only needs 2 visits to have your metal free crown.

  The Zirconia, Bruxzir, E-Max among others (all of these are porcelain brands), are lightly more expensive that metal porcelain crowns, but is an investment that is worth it considering that you will never start to see a gray margin on the edge of the crown, they are more aesthetic, there is no risk of toxicity due to its metal or smell, they last approximately around 10 years if you take good care if them and they have a more conservative preparation therefore maintaining your dental structure for longer time.  

Muelas del Juicio

On June 22, 2016

 Las molares del juicio son los últimos dientes en formarse, aproximadamente erupcionan fuera de la encía entre los 17 y 22 años de edad, pero si no hay suficiente espacio en la boca para acomodarlos o si estas molares vienen en una mala posición (inclinadas) pueden llegar a provocarnos bastantes molestias y dolor.  Los problemas más comunes que suelen causar las molares del juicio son caries, ya sea sobre ellas o al diente vecino, infección, mal aliento, problemas de encías y apiñamiento. También por encontrarse al fondo de la boca se vuelve más complicado el cepillado lo que favorece la acumulación de bacterias.

  En mi experiencia yo recomiendo extraer estas molares entre los 16 y 24 años de edad, porque a esta edad las raíces están menos desarrolladas y las complicaciones son mínimas al momento de removerlas. Además siendo jóvenes, el tejido cicatriza más rápido que siendo adultos.

  La manera en que evaluamos cómo se encuentran sus molares del juicio es con una consulta de rutina, donde tomamos una radiografía con la cual podemos diagnosticar  si es mejor mantener la muela o extraerla.

  Si su molar viene en buena posición se realiza una extracción de rutina; si la molar viene inclinada o bloqueada por hueso, se necesita realizar una cirugía bucal.

La muelas del juicio son impredecibles y pueden llegar a causar molestia en cualquier momento, tomar un analgésico  sólo lo aliviará momentáneamente, es mejor quitar el dolor de raíz.
