The following are general guidelines for the eruption of the baby teeth:. The first tooth to erupt is usually a middle, front tooth on the lower jaw, known as the central incisor. This is followed by the second central incisor on the lower jaw. The above is followed by the first 4 molars, and the remaining bottom 2 lateral incisors.
Lateral incisors are beside lateral to the central incisors. Next, the 4 first molars come in. Usually, after the child reaches 2 years old, the 4 second molars the last of the baby teeth appear. The teeth on the upper jaw usually erupt 1 to 2 months after the same tooth on the lower jaw. There are a total of 20 primary teeth. Usually, about 1 tooth erupts per month once the teeth have started coming in.
There is normally a space between all the baby teeth. This leaves room for the larger permanent teeth to erupt. The eruption sequence can vary quite a bit from child to child. So, don't become overly concerned if your child's teeth do not follow the pattern above. However, if teeth fail to come in a year after the expected time, check with your child's dentist to make sure they are developing properly.

As teeth flex under pressurethe arrangement of teeth touching each other, known as occlusioncauses tension on one side of the Teeth Teeth Teeth - Beavue Cleavue - Different Kings (CDr and compression on the other side of the tooth.
This is believed to cause V-shaped depressions on the side under tension and C-shaped depressions on the side under compression. When tooth destruction occurs at the roots of teeth, the process is referred to as internal resorptionwhen caused by cells within the pulp, or external resorptionwhen caused by cells in the periodontal ligament. Discoloration of teeth may result from bacteria stains, tobacco, tea, coffee, foods with an abundance of chlorophyllrestorative materials, and medications.
Green stains also result from foods with chlorophyll or excessive exposure to copper or nickel. Amalgam, a common dental restorative material, may turn adjacent areas of teeth black or gray.
Long term use of chlorhexidinea mouthwash, may encourage extrinsic stain formation near the gingiva on teeth. This is usually easy for a hygienist to remove. Systemic disorders also can cause tooth discoloration. Congenital erythropoietic porphyria causes porphyrins to be deposited in teeth, causing a red-brown coloration. Blue discoloration may occur with alkaptonuria and rarely with Parkinson's disease. Erythroblastosis fetalis and biliary atresia are diseases which may cause teeth to appear green from the deposition of biliverdin.
Also, trauma may change a tooth to a pink, yellow, or dark gray color. Pink and red discolorations are also associated in patients with lepromatous leprosy. Some medications, such as tetracycline antibiotics, may become incorporated into the structure of a tooth, causing intrinsic staining of the teeth. Tooth eruption may be altered by some environmental factors. When eruption is prematurely stopped, the tooth is said to be impacted. The most common cause of tooth impaction is lack of space in the mouth for the tooth.
Tooth ankylosis occurs when the tooth has already erupted into the mouth but the cementum or dentin has fused with the alveolar bone. This may cause a person to retain their primary tooth instead of having it replaced by a permanent one.
Some systemic disorders which may result in hyperdontia include Apert syndromecleidocranial dysostosisCrouzon syndromeEhlers—Danlos syndromeGardner's syndromeand Sturge—Weber syndrome.
Microdontia of a single tooth is more likely to occur in a maxillary lateral incisor. The second most likely tooth to have microdontia are third molars. Macrodontia of all the teeth is known to occur in pituitary gigantism and pineal hyperplasia.
It may also occur on one side of the face in cases of hemifacial hyperplasia. There are many types of dental anomalies seen in cleft lip and palate CLP patients. Both sets of dentition may be affected however they are commonly seen in the affected side. Most frequently, missing teeth, supernumerary or discoloured teeth can be seen however enamel dysplasia, discolouration and delayed root development is also common.
In children with cleft lip and palate, the lateral incisor in the alveolar cleft region has the highest prevalence of dental developmental disorders. By correctly coordinating management invasive treatment procedures can be prevented resulting in successful and conservative treatment.
There have been a plethora of research studies to calculate prevalence of certain dental anomalies in CLP populations however a variety of results have been obtained. In a study evaluating dental anomalies in Brazilian cleft patients, male patients had a higher incidence of CLP, agenesis, and supernumerary teeth than did female patients.
In cases of complete CLP, the left maxillary lateral incisor was the most commonly absent tooth. Supernumerary teeth were typically located distal to the cleft. Missing teeth were observed in Supernumerary teeth were observed in The incidence of microdontia, dilaceration, and hypoplasia was significantly higher in bilateral CLP patients than in unilateral CLP patients, and none of the anomalies showed any significant sexual dimorphism. It is therefore evident that patients with cleft lip and palate may present with a variety of dental anomalies.
It is essential to assess the patient both clinically and radiographically in order to correctly treat and prevent progression of any dental problems. It is also useful to note that patients with a cleft lip and palate automatically score a 5 on the IOTN index for orthodontic need and therefore are eligible for orthodontic treatment, liaising with an orthodontist is vital in order coordinate and plan treatment successfully.
