Frequently asked questions
1How long does orthodontic treatment usually take?
Treatment typically takes 12–24 months, but the duration depends on the severity of the malocclusion, treatment method, and how consistently the patient follows instructions.
2Why are retainers important after orthodontic treatment?
Teeth can naturally shift after treatment. Retainers help maintain the corrected tooth positions and reduce the risk of orthodontic relapse.
3Can a tooth become infected again after root canal treatment?
Yes. Reinfection can occur due to untreated canals, leakage, new decay, cracks, or inadequate restoration. Proper cleaning, sealing, and final restoration are essential for long-term success.
4How do I know whether I need veneers or crowns?
Veneers may be suitable for improving tooth shape, color, and minor aesthetic imperfections when sufficient healthy enamel remains. Crowns are generally considered when a tooth is significantly weakened or structurally compromised.
5What are the options for replacing missing teeth?
Depending on the number and condition of missing teeth, options may include dental implants, implant-supported bridges, conventional bridges, or removable dentures.
