Dental treatments are currently based on conservative approaches, using inorganic materials and related appliances. Biomaterials including both natural/chemical play a vital role in dental tissue engineering. Biomaterials are utilized for fabricating frameworks known as scaffolds, matrices, or constructs to afford optimal dental tissue regeneration. The identification/utilization and development of appropriate biomaterials to optimize and regenerate these hybrid dental tissues is a greater challenge for dental researchers. Biomaterials are tailored to offer good interconnected porosity, large surface area, mechanical strengths, varying surface characterization, and different geometries for effective dental tissue regeneration. A literature search was made on articles, which are available in Pubmed, using key searches, such as biomaterials, tissue regeneration, tissue engineering, regenerative dentistry, periodontal regeneration, and hard/soft dental tissue regeneration. Papers were mostly searched from 2000 onward. In this review paper, we discussed about dental diseases, applications, and tissue engineering strategies in dentistry, biomaterials used in tissue engineering for tooth regeneration, bone regeneration, enamel regeneration, periodontal tissue regeneration, oral mucosa regeneration, salivary gland regeneration, and dentin/dental pulp regeneration.
