Complex nanodevices and nanorobots will be created in the next few years, first from biological materials and then from more durable materials such as diamond.
Because the human body is made up of molecules, molecular nanotechnology will aid in the resolution of medical issues and the improvement of human health at the molecular level.

The medical and dental repercussions are enormous.
Precision cellular and molecular manipulations might be possible with programmable nanorobots.
Medical nanorobots have been proposed for genotological applications such as mechanically reversing atherosclerosis, improving respiratory capacity, enabling near-instantaneous homeostasis, supplementing the immune system, rewriting or replacing DNA sequences in cells, repairing brain damage, and resolving gross cellular insults caused by irreversible processes or cryogenic storage of biological tissues.

social issues of nanotechnology
Nanorobots do not increase the risk of sepsis or septic shock since they degrade pathogens into harmless sugars, amino acids, and so on.
Nanorobotics
A surgical nanorobot programmed or overseen by a human surgeon might perform semiautonomous on-site surgery inside the human body.
A device like this might look for pathology, diagnose and cure lesions using nanomanipulation, and communicate with the supervising surgeon via coded ultrasonic signals.

Nanodentistry
To preserve oral health, nanodentistry employs nanomaterials and biotechnology, including tissue engineering and dental nanorobotics.
New dental treatment options may include local anaesthesia; dentition renaturalization; permanent hypersensitivity cure; comprehensive orthodontic realignments in a single office visit; covalently bonded diamondized enamel; and mechanical dentifrobots.
Dental nanorobots may employ particular motility processes to navigate through human tissue, collect energy, detect and control their environment, accomplish safe cytopenetration, and monitor, disrupt, or change nerve impulse flow in individual nerve cells in real time.
In reaction to sensor inputs, onboard nanocomputers manage nanorobot actions.
The dentist may also use sound waves or other methods to communicate orders to in-vivo nanorobots.
Anesthesia-inducing
Dentists employ a colloidal solution containing millions of active analgesic dental nanorobot 'particles' on the patient's gingivae to generate mouth anesthesia.
The ambulating nanorobots reach the dentin by migrating into the gingival sulcus and softly passing through the lamina propria, a 1-3 micron thick layer of loose tissue at the cementodentinal junction after contacting the crown or mucosa.
When nanorobots approach dentin, they enter 1-4 millimeter dentinal tubule holes and proceed toward the pulp, guided by chemical gradients, temperature differentials, and positional navigation, all as directed by the dentist's onboard nanocomputer.
nanotechnology in medicine benefits
There are various pathways near the CEJ, between the junction and the pulp, and through the pulp.
The diameter of the tubule increases as it approaches the pulp, which may improve nanorobot movement.
The number and size of circumpulpal tubule openings differ (tubule density: 22,000 mm DEJ, 37,000 mm square midway, and 48, 000 mm square near pulp).
For example, tubule branching patterns might be difficult to traverse between primary and irregular secondary dentin, as well as regular secondary dentin in young and old teeth (sclerosing).
Natural cells that move around and inside teeth, such as human gingival and pulpal fibroblasts, cementoblasts of the CDJ, bacteria inside dentinal tubules, odontoblasts near the pulp dentin border, and lymphocytes within the pulp or lamina propria, suggest that such a journey should be possible by cell-sized nanorobots with similar mobility.
Once implanted in the pulp and regulating nerve impulse flow, the dentist may instruct the analgesic dental nanorobots to turn off tooth sensitivity.
On the handheld controller, the selected tooth becomes numb.
After dental treatments, the dentist instructs the nanorobots to restore complete sensation, reestablish nerve traffic regulation, egress, and aspirate.
Dental analgesics give better patient comfort and reduced anxiety; no needles; more analgesic selectivity and controllability; and rapid and completely reversible switchable action.
Dentist
By utilizing an affordable desktop manufacturing facility in the dentist's office, nanorobotic manufacture and installation of a biologically autologous whole replacement tooth that includes both mineral and cellular components should become feasible within the time and economic constraints of a typical office visit.
To mimic the natural biomineralization process of tooth enamel, Chen et al.

Dentin hypersensitivity: nonsensitive teeth have eight times as many tubules and a larger diameter than hypersensitive teeth.
Reconstructive dental nanorobots could occlude specific tubules in minutes, allowing for a quick and long-lasting treatment.
Teeth reshaping
Orthodontic nanorobots could manipulate periodontal tissues in minutes to hours to straighten, rotate, and relocate teeth.
Renaturalization
This technique has the potential to become popular in cosmetic dentistry.
This trend could start with patients who want their old dental amalgams excavated and their teeth remanufactured with native biological materials, and it could progress to full coronal renaturalization procedures in which all fillings, crowns, and other 20th century modifications to the visible dentition are removed and the affected teeth remanufactured to look like original teeth.
Cosmetics and longevity
Upper enamel layers can be replaced with biocompatible covalently linked artificial materials such as sapphire or diamond, which are 20-100 times harder than natural enamel.
Pure sapphire and diamond, which are brittle and prone to fracture, could be strengthened as part of a nanostructured composite material.
Dentifrobots may patrol supragingival and subgingival surfaces at least three times per day, metabolizing trapped organic matter into harmless and odorless fumes and debriding calculus.
Dentifrobots can detect and remove harmful bacteria in plaque and elsewhere, while allowing 500 species of harmless dental microflora to thrive.
