Number 1: 3rd Molar commonly known as wisdom tooth. Number 2: 2nd Molar. Number 3: 1st Molar. Number 4: 2nd
The dentist's scoring between 0 to 4 indicates zero being the best you can get meaning your gums are in excellent condition, and four indicate gum disease. The numbers you hear your dentist calling are the depths of the pockets around the teeth in millimeters. Smaller, tighter pockets usually mean healthier gums.
Behind the canines lie the bicuspids (or premolars). The bicuspids are #4, 5, 12, 13 (upper jaw) and #20, 21, 28, 29 (lower jaw). Bicuspids are a sort of "in-between tooth," with the properties of both the canine and molar teeth. These teeth transfer food from the canines to the molars for proper grinding.
The fourth and fifth teeth have one root on the bottom jaw (usually) and the top fourth tooth usually has two small roots, like the tops of rabbit ears. The fifth tooth usually has one root. The sixth and seventh teeth (molars) usually have two roots on the bottom jaw and three roots on the top jaw.
1-4 The incidence of molars with four roots are reported to be less than 1%. 5 The treatment of a third molar with aberrant root configuration can pose a diagnostic and clinical challenge to the dentist.
SEVERE / Grade 4
Severe tartar formation and gum disease is present. Toxic debris and inflammation have caused extensive tissue death. Roots are infected, abscessed, and rotten. The thin wall of bone surrounding teeth has deteriorated, and many teeth are loose.
Stage 4: Involvement of the Pulp
If the pulp of a tooth gets infected with bacteria, pus then forms which inadvertently kills the blood vessels and nerves in the tooth. This is commonly known as a toothache and can cause constant pain. At this stage, the most common course of treatment is root canal therapy.
A 1 means you have some mild bleeding and plaque at the edges of your teeth. 2 means dead plaque hardened around your teeth, requiring gentle cleaning, while 3 means you might have gum disease. A score of 4 means you have gum disease that will need treatment.
A dental crown is a tooth-shaped cap that restores a decayed, broken, weak or worn-down tooth. Dentists also use crowns to cover dental implants and root canal-treated teeth. Made from a variety of materials, including metal, resin and porcelain, crowns last between five and 15 years with proper care.
Universal method – starting at the rear right upper molar and preceding to the rear left upper molar, teeth are numbered 1 to 16. Then, the bottom teeth are numbered from left to right 17 to 32. This numbering system allows for all 32 teeth, including wisdom teeth, to be present.
Teeth Numbers
To break this down, a number is used to denote a specific tooth. These are numbered according to the internationally designed two-digit FDI (Federation Dentaire Internationale) numbering system that is used by dentists, not just in Australia. Every tooth has a two-digit number assigned to it.
Each tooth in the human mouth is related by a meridian to an organ in the body. When an organ or system becomes diseased or infected, the associated tooth most likely will express some type of symptom as well. By referring to this meridian tooth chart, you can see the connections between your teeth and your organs.
Teeth Numbering:
The upper teeth are numbered from 1-16 from right to left and the lower teeth are numbered 17-32 from left to right. Therefore, 1,16,17 and 32 would refer to your wisdom teeth and 6-11 and 22-26 would be your anterior teeth in the upper and lower jaws respectively.
However, in most cases code 4 is likely to be deeper into dentin than code 3. Cavitation in opaque or discolored enamel are exposing the dentin beneath. The tooth viewed wet may have darkening of the dentin visible through the enamel.
Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or holes. Cavities, also called tooth decay or caries, are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks and not cleaning your teeth well.
The biggest factor a dentist looks at when deciding if a tooth can be saved is how much “good” tooth structure there is left. If the tooth is broken at the gumline and has a big cavity that goes down to the bone then there is little hope that the tooth can be saved.
Stage 4: Progressive Periodontitis
The end result — eating and even smiling is hard and painful, and you may lose most of your teeth. However, it's important for you to know that all of this is preventable with regular oral hygiene and routine oral cleaning at the dental clinic.
Stage 4: Advanced Periodontal Disease. This is the final stage of periodontal disease and at this point the infection has evolved into disease-causing bacteria. This can lead to several issues as gums which ooze pus, teeth significantly loosening, severe pain when chewing, and major bone loss.
Explanation of the correct option : Plaque is a disease which attacks the teeth. Plaques a sticky substance that develops on your teeth and gums caused by bacteria. It causes tooth decay.
Although any tooth can have decay form and need a root canal, the back molars are the most common teeth to need root canals.
The canines have a single long root and a single root canal. The canine roots are the longest root of all teeth. Furthermore, the upper canines have longer roots when compared to the mandibular canines. The canines serve to support the incisors.
Type II maxillary molars have four, shorter, parallel running roots with blunt apices.
