Clear, evidence-based explanations of dental science, procedures, and terminology.
DentoHub Dental is an independent reference website about dentistry as a subject: its specialties, common procedures, technologies, and the science behind everyday oral care. It is not a clinic and does not sell, book, or advertise dental services. Everything here is explanatory material compiled from widely accepted professional and public-health sources.
Dentistry is the branch of medicine concerned with the teeth, gums, and the structures of the mouth and jaw. What looks from the outside like a single profession is in practice a cluster of distinct disciplines, each with its own training pathways, instruments, and evidence base. Understanding that structure helps patients interpret diagnoses, referrals, and treatment plans.
Most national systems recognise a similar core set of specialties. Endodontics deals with the dental pulp and root canals; periodontics with the gums and supporting bone; orthodontics with tooth position and bite; prosthodontics with crowns, bridges, and dentures; oral and maxillofacial surgery with extractions and jaw surgery; and paediatric dentistry with children's oral health. General dentists coordinate most care and refer to specialists when a case exceeds routine complexity.
Almost every common dental procedure makes more sense once the basic anatomy of a tooth is clear. A tooth is not a uniform block of bone-like material; it is a layered structure, and each layer behaves differently when decayed, fractured, or infected.
The visible crown is covered by enamel, the hardest tissue in the human body, which protects the softer dentin beneath. At the centre lies the pulp — living tissue containing nerves and blood vessels — which extends through narrow root canals into the jawbone. Because enamel contains no living cells, it cannot repair itself; damage to it is permanent and must be managed by prevention or restoration.
Root canal treatment — formally, endodontic therapy — is the procedure used when the pulp inside a tooth becomes inflamed or infected, usually through deep decay, cracks, or trauma. The goal is to remove the diseased tissue, disinfect the canal system, and seal it so the natural tooth can be kept rather than extracted. A typical course involves diagnosis with X-rays, local anaesthesia, isolation of the tooth, cleaning and shaping of the canals, and a sealed filling, often followed by a crown on back teeth.
The procedure has a reputation for pain that modern evidence does not support: with adequate local anaesthesia, most patients report it as comparable to having a filling placed. Success rates in published studies are high, and a treated tooth restored properly can remain functional for decades. The alternative — extraction followed by a bridge, denture, or implant — is generally more invasive and more costly over time.
Over the past three decades dentistry has shifted from analogue to digital workflows. Digital radiography reduced radiation doses compared with traditional film and made images available instantly. Cone-beam computed tomography (CBCT) added three-dimensional views of bone, roots, and nerve canals, which is particularly valuable in implant planning and complex endodontics.
Intraoral scanners now capture the shape of teeth as 3D models, replacing many physical impressions. Combined with CAD/CAM milling or 3D printing, this allows crowns, aligners, and surgical guides to be designed and manufactured digitally — sometimes within a single visit. These tools change precision and logistics, but they do not replace clinical judgement; diagnosis and treatment planning still rest on examination and evidence.
The two most common oral diseases — dental caries and periodontal disease — are largely preventable, and the strongest evidence supports a short list of habits rather than any branded product. Fluoride is central: its effectiveness in toothpaste and, where available, in community water fluoridation is among the most thoroughly studied questions in public health.
Regular professional examination matters because early decay and gum disease are often painless. Recall intervals are best set individually: guidance such as that from NICE in the United Kingdom recommends intervals from roughly 3 to 24 months depending on risk, rather than a universal six-month rule.
Dental marketing often borrows the vocabulary of science. Terms such as 'painless', 'permanent', or 'Hollywood smile' describe aspirations, not measurable outcomes, and no treatment is free of risk or guaranteed for life. A reliable source states what a procedure can and cannot do, cites evidence, and discloses uncertainty.
When evaluating any dental website — including this one — check whether it separates explanation from promotion, whether its claims can be traced to professional bodies or peer-reviewed literature, and whether it pressures the reader toward a purchase. Independent references inform; they do not book appointments or rank 'the best' clinics.
