Treatments

Care by what you need

Keep healthy teeth healthy, fix a problem, replace missing teeth, or change how your smile looks — every treatment page explains the option in plain language.

Keep teeth healthy

Exams, cleanings, and everyday dentistry that keeps small problems small.

Fix a problem

A broken, aching, or missing tooth has more repair options than most people expect.

Replace missing teeth

From a single implant to a full arch — and the honest tradeoffs between the options.

Love your smile

Veneers, whitening, and aligners — with plain-language pages on what each can and can't do.

Comfort & sedation

If dental visits are hard for you, sedation dentistry exists for exactly that.

The founding standard

Every claim on this site is verifiable — credentials on federal record, prices published by the office that honors them, and nothing invented in between.

Complete Dental Centers was founded by Dr. Sameer Aljanedi, DDS — the clinician named across all four practices, with his license and active Huntington Beach practice on record in the federal NPI registry.

It's why the offices keep their own names, their own membership plans, and their own phone lines. The group stands behind them; it doesn't blur them together.

Why the group

What one group, four offices gets you

  1. The full range of care

    Checkups, kids' visits, crowns, implants, Invisalign — the group covers the full range, with each office's treatment menu published on its location page.

  2. Offices patients know by name

    Beachside, Pacifica, Marina Dentistry, Rio Hondo — established practices that keep their own names and teams, each with its own location page.

Treatment spotlight

Dental implants

A dental implant replaces a missing tooth from the root up: a titanium post in the jaw, a connector, and a crown built to match your bite and your remaining teeth.

The implants page explains how treatment works, why it takes months rather than weeks, and what actually drives the cost — before you ever sit in a chair.

Paying for care

Membership and financing, office by office

No two offices publish identical terms — each office's are listed under its own name.

Membership plans

Every office publishes a membership plan for patients without dental insurance — a flat yearly fee that covers routine preventive care and discounts other treatment. Prices are the same at every office; what each plan includes differs, on purpose.

Compare membership plans

Financing

Every office works with third-party financing partners, so larger treatment can be paid over time — subject to credit approval. Lender rosters differ by office.

Everyone from the front desk to the technicians, doctors, and management was kind, professional, and attentive. It reminded me exactly why I’ve been a loyal patient for over a decade.”

How booking works

  1. Choose your office

    Four practices across three areas. Pick the closest — or the one you already know by name.

  2. Request an appointment

    Send the online request or call the front desk. The form is a request, not a confirmed booking.

  3. The office confirms

    Your office calls back to set the time and tells you exactly what to bring.

Questions

Common questions

Which office should I choose?

Start with geography. The four offices sit in three different parts of Southern California, and for most patients the nearest one is the right one.

  • Beachside Dental Group and Pacifica Dental both serve Huntington Beach and coastal Orange County — they share one building at 18800 Main St, each in its own suite.
  • Marina Dentistry serves Marina del Rey and the Westside of Los Angeles — Venice, Playa Vista, Santa Monica, Culver City.
  • Rio Hondo Dental Group serves Downey and southeast LA County — Pico Rivera, Bellflower, Norwalk, South Gate, and is the group's office for Denti-Cal and Medi-Cal patients.

Two useful tie-breakers: the treatment menus differ by office (each location page lists what that office offers), and Rio Hondo is the group's office for Denti-Cal and Medi-Cal patients. If you're still unsure, call whichever office is closest — the front desk will tell you plainly whether another office is a better fit.

Are all four offices the same practice?

They are four separately operated practices that belong to one group, Complete Dental Centers, founded by Dr. Sameer Aljanedi, DDS.

Each office keeps its own name, its own phone line, its own team, and, importantly for your wallet, its own membership plan, financing partners, and insurance arrangements. Those details genuinely differ between offices, which is why this site describes them per office rather than as one blended policy.

This site's job is to help you understand the group and choose the right office. Once you've chosen, that office is your practice — see all four locations or request an appointment and pick your office on the form.

Can I switch from one office to another?

Yes. You can book at whichever of the four offices suits you — patients move between them when they relocate or when a treatment is offered at one office and not another.

Three practical notes before you switch:

  • Each practice operates independently, so your records do not move automatically. Call the office that treated you and ask them to transfer your chart and X-rays.
  • Membership plans are sold per office and generally apply at the office that sold them — confirm with both offices before assuming benefits carry over.
  • Treatment menus differ. Check the new office's location page, or call, to confirm it offers the care you need.

Phone numbers for all four offices are on the contact page.

How do the membership plans work?

A membership plan is a flat yearly fee paid directly to an office that covers your routine preventive care (exams and cleanings) and discounts other treatment. It is designed for patients without dental insurance, and it is not dental insurance.

The prices match; the plans still differ. All four offices publish the same price tiers — $199, $299, and $399 per year (individual, two people, family). What each plan includes differs by office: Pacifica, for example, includes three cleanings a year instead of two, and discount levels vary.

A plan generally applies only at the office that sold it, so pick your office first, then enroll. Full per-office details are on the membership page — and the office's front desk can confirm current terms when you call.

How do I book an appointment?

Two ways: call the office directly, or send an online request and let the office call you back to set the time.

  • Call — fastest, and the right choice if you're in pain. Every office's number is on the contact page and on its location page.
  • Online — use the appointment request form, choose your office, and the team follows up to confirm a time. The form is a request, not a confirmed booking.

Not sure which office? Start with choosing an office.

What happens at my first visit?

Expect an exam and a conversation, not a hard sell. A typical first visit includes a review of your health history, a full examination, X-rays where they're needed, and a plain-language discussion of what the dentist found and what, if anything, to do about it.

Whether a cleaning happens the same day depends on your gum health: a routine cleaning often fits into the first visit, while gum disease may call for a different kind of cleaning scheduled separately. The office will tell you which applies to you before anything starts.

More detail, including per-office forms, is on the new patients page.
