The Dangers Of Acid In Food and Drink

19th July, 2012

Acidity is measured using the PH scale. This rates acidity on a scale from pH1, which is extremely acid, to pH14, which is extremely alkali and Neutral is rated as pH7.

Tooth enamel dissolves at an acidity below pH5.5. Dentine, which makes up the inside of the crown plus the root dissolves at pH6. So, if we start with the mouth being neutral and then change it to a pH of 3.5 by drinking an acid drink, the tooth surface can be dissolved because the tooth is bathed in something that’s a hundred times more acidic than needed to dissolve it!

An acidic diet, combined with abrasive whitening toothpaste will strip the enamel leading to a rough hollow in the tooth that will collect stains. The only sensible solution here is to clean away the stain and then fill the area in with white filling material. But the white filling material will eventually pick up stain itself.

Remember the cut off for safety is at 5.5 for enamel and 6 for dentine. And what happens if the tooth surface is eaten away is the teeth become very senstitive!

Exploring Your Options For Replacing Missing Teeth

12th July, 2012

Tooth loss can possibly lead to further tooth loss if not addressed as the other teeth are exposed to infection and even further movement once one has gone missing. 

When looking to fill a gap you have many options but the one you will require rather depends exactly on where the tooth has been lost. A bridge is a brilliant replacement for lost teeth as you are still left with different options. If a tooth has gone between two others, a Maryland bridge is one of the more popular choices. It comes as a single tooth with two pontics which are cemeneted on to the back of the neighbouring teeth, This process causes no damage to your own healthy teeth.

Another option is a bridge that is a new tooth bonded to two crowns which are cemented onto the surrounding teeth. After a bridge is fitted it is crucial to maintain an excellent oral hygeine routine it is an acquired technique and takes a little bit of effort to get right at first and you will have to invest in the right tools such as a good toothbrush and interdental brushes,  But get it right and a dental bridge will not only restore the look of your mouth, it will keep the health of your mouth up and running while it is in place!

Explaining Teeth Extraction In Sutton



 

Teeth extraction is the removal of teeth from the bone that they are developed on. There are different reason why teeth can be extracted ranging from a decayed root that cannot be restored, an impacted tooth, diseases of the gum that work otherwise not heal if the tooth is not extracted to misaligned teeth that are in the way of other developing teeth. Tooth roots are held to the bone by the periodontal ligament in the socket in which it rests inside the alveolar bone. Other possible reasons for teeth extraction are nerve injury.

Depending on the position of the tooth to be removed, there will be different instruments that would be used in making this happen. Operations involving the removal of a visible tooth are called simple extractions and the tools that are used are as well simple. Local anesthesia is widely used for simple teeth extractions. More complicated instruments would be used to remove impacted teeth that did not get to the surface of the gum. These would usually involve surgical operations since the teeth are not visible.

In simple teeth extractions, there are two instruments used to extract teeth and they are dental extraction forceps and the periosteal elevator. Each of these has a different purpose, and considering that the tooth is visible, it is only pressure that is applied to weaken the periodontal ligament and break it to let go of the tooth. The dental extraction forceps are used to hold the part of the tooth that is above the gum and apply this pressure while the elevator is used to lever out and pull the tooth from the socket it is developed in.

Teeth that did not erupt to above the gum tissue or have broken close to the alveolar bone, a surgical operations would have to be applied and this kind of extraction is called the atraumatic extraction. If the teeth developed beyond the bone, then a blade or incisor would be required to cut the gum tissue to expose it, usually a drill would be used to break the tooth to pieces to ease the removal. The exact instrument that is used to drill is called an osteotome. Another instrument is the periotome which can be manual or machine operated and is used to remove the bone tissue.

Present day oral surgeons have instruments that are meant to have the least damage to the alveolar bone that the tooth is resting on in atraumatic teeth extractions. This is in the view that the patient might need an implant to fill up the space that has been left by the extracted tooth. Despite the instruments used in teeth extractions, oral surgeons need to take the utmost care not to injure the buccal bone and buccal plate.

Teeth extraction can be a costly venture and replacement with implants is even more costly. Considering most teeth extractions are done due to infections on the tooth, it is necessary to try to keep the surgeon away by brushing regularly and thoroughly, with regular visits to your dentist and hygienist.
