Primary tooth

Deciduous teeth, otherwise known as milk teeth, baby teeth, temporary teeth and now more commonly primary teeth, are the first set of teeth in the growth development of humans, which is called teething. They develop during the embryonic stage of development and erupt—that is, they become visible in the mouth—during infancy. They are usually lost and replaced by permanent teeth, but in the absence of permanent replacements, they can remain functional for many years.

Primary teeth are smaller, whiter, and prone to wear than permanent teeth. Around six months after birth, the first teeth erupt, and the primary dentition is complete by two and a half years old. Shedding starts around age five or six and is done by age thirteen. The primary teeth are gone when the roots of the permanent teeth grow toward the mouth cavity.

In humans, each jaw has four incisors, two canines, and four molars, totaling 20 teeth in the primary dentition. The premolars, also known as bicuspid teeth, take the place of the primary molars in the adult dentition. There are 32 teeth in the permanent dentition. The 12 adult molars erupt behind the primary teeth and do not replace any of these.

Hall Technique

Image
The Hall Technique is a non-invasive dental treatment for managing decayed baby molars without the need for injections or drilling, significantly improving the patient's comfort. This method involves sealing the decay under preformed stainless steel crowns , aligning with modern, biologically-oriented dental care strategies. Notably preferred by children, parents, and dentists , this technique is backed by evidence demonstrating its effectiveness and acceptability, providing a more patient-friendly alternative to traditional fillings . Despite initial concerns about potential progression of sealed caries, long-term studies have shown that the Hall Technique can successfully arrest decay, reducing the risk of pain and infection associated with untreated carious teeth . Originating from the work of Dr. Norna Hall in Scotland, this technique simplifies the restoration of primary molars by cementing a crown directly over the decayed tooth without prior caries removal or tooth prepa...

Replacing multiple teeth with dental implant supported prostheses. Is that possible?

Replacement of multiple teeth follows generally the same process as replacement of one tooth. However, if two adjacent teeth are required to be replaced they can be supported on a single implant. The entire set of teeth in a jaw can be supported on a minimum of four implants, while in some cases up to […] Original post here: Replacing multiple teeth with dental implant supported prostheses.
