A denture can look perfectly fine but start to feel progressively looser as the years go by. If this is your experience, you are not alone. After tooth loss, the jawbone and soft tissues continue to resorb and remodel. That slow, natural change can leave a once secure denture rocking, rubbing, or slipping at inopportune moments. At Sullivan Denture Centre in Surrey, we focus on returning comfort and confidence with precise fit restoration. Two reliable paths do most of the heavy lifting: a reline or a rebase. Understanding the difference helps you know what to expect, how quickly we can help, and how to keep your denture fitting well over time. This guide explains why fit changes occur even when materials look sound, how we determine whether a reline or rebase is right, what a same-day reline visit involves in our on-site lab, how long results typically last, and when to book your next check. Why dentures loosen over time Your denture rests on living tissue, not on an unchanging surface. Once teeth are removed, the alveolar bone that supported them no longer receives the same stimulation. The body naturally remodels that bone, a process called resorption, and the overlying gums adapt as well. These gradual changes can: Reduce the height and width of the ridge under your denture Alter the contour of soft tissues Change how saliva distributes, affecting suction and comfort Even high-quality, well-made dentures will feel different as the foundation beneath them shifts. That is why a denture can appear intact while becoming loose or creating sore spots. Reline vs. rebase, in plain terms Both services refresh fit. The difference lies in how much of the denture is updated. Reline: We resurface or replace the internal fitting surface of your existing denture so it conforms to your current gum contours. The teeth and the outer shape remain the same. A reline is ideal when the denture teeth, bite, and acrylic base are otherwise in good condition, but the inside has lost close contact with your tissues. Rebase: We replace the entire acrylic base while keeping your current denture teeth and their arrangement. A rebase is chosen when the base has degraded, is discoloured or porous, has small fractures, or when the shape changes needed exceed what a reline can correct. It strengthens and refreshes the foundation without changing the tooth setup you are used to. When a reline is enough We typically recommend a reline when: The denture is generally sound, but it feels loose or rocks You have developed sore spots from uneven pressure Your bite still feels correct and the teeth show normal wear The acrylic base is intact without cracks or significant staining You recently had extractions or an immediate denture and your tissues are still settling In these cases, updating the internal fit restores close contact, improves suction and stability, and relieves pressure points without a full remake. When a full rebase is the better answer We recommend rebasing when: The acrylic base has microfractures, has become porous or discoloured, or has absorbed odours The denture has been repaired multiple times and needs structural renewal There are pronounced anatomical changes that a reline alone cannot adapt to The base thickness or shape requires correction for durability and stability You need a stronger foundation to support your current teeth long term Rebasing preserves the tooth arrangement you like while giving you a fresh, durable base. Our assessment process Every fit restoration begins with a careful evaluation by a licensed denturist. At Sullivan Denture Centre, your clinician examines: Overall denture condition, tooth wear, bite relationship, and base integrity Tissue health, ridge anatomy, and areas of soreness or instability Retention and stability during speech and function We use precise impressions or digital scans to capture your current anatomy. Our on-site lab allows for workflows with enhanced accuracy and speed. Based on clinical findings, we will recommend a reline or a rebase and provide a clear estimate and timeline.

Many patients simply search for a denturist near me, but a direct visit to our site gives you the most accurate picture of our services and on-site lab capabilities. What a same-day reline visit involves Our on-site laboratory allows many relines to be completed the same day, minimizing disruption. A typical reline appointment includes: Fit check and planning : Your denturist identifies pressure points and confirms that a reline will meet your goals. Precision impression or scan : We capture your current tissue contours while you gently close into a comfortable bite. In-lab processing : Your denture goes to our in-house lab for controlled processing of the new internal surface. Having the denturist and technician side by side supports accuracy and quick adjustments. Refitting and polish : We reseat your denture, assess comfort, refine pressure points, and polish for a smooth, clean finish. Home care and follow-up : You receive instructions for cleaning and what to expect as your tissues settle. Minor adjustments, often complimentary, are scheduled as needed. Most patients leave the same day with a noticeably more secure fit. If your case is more complex, we will explain the steps and timeline before beginning. Turnaround for rebasing A rebase is a more involved laboratory process than a reline. Because we replace the entire acrylic base while preserving the teeth, we plan the sequence to protect accuracy. Many cases have a prompt turnaround with our in-house lab; if your situation requires additional steps, we will outline a practical schedule and arrange a comfortable temporary solution when appropriate. How long results typically last Tissues continue to change gradually. As a general guideline: Relines are commonly needed every 1 to 3 years, depending on bone resorption, health changes, and daily wear patterns. Rebases refresh the foundation and can extend the service life of your current teeth, but timelines vary with anatomy, hygiene, and function. Complete replacement is often evaluated around the 5 to 10 year mark, especially when teeth are worn, bite relationships shift, or facial support changes. Your denturist will tailor recommendations to your case and provide clear signs to watch for, such as new sore spots, looseness, or speech changes. Follow-up and ongoing care We recommend annual fit checks. A short visit allows us to detect early changes, relieve pressure points, and plan the right intervention before problems escalate. Some patients benefit from bi-annual reviews, particularly during the first year after extractions or when managing significant resorption. Proper daily cleaning with non-abrasive cleansers, careful handling, and drying your denture overnight can also protect fit and materials. If cost or coverage is a concern, ask us about CDCP support, pre-authorization for partials, and direct billing. We will help you understand what is included and how frequency limits may apply to relines. Short FAQ When is a reline enough and when is a rebase needed? A reline is appropriate when the denture is structurally sound and only the internal fit needs updating. A rebase is indicated when the acrylic base is worn, cracked, porous, or when anatomical changes exceed what a reline can address. How do jawbone and tissue changes affect fit? Bone resorption and soft tissue remodeling gradually reduce and reshape the ridge that supports your denture. Even a well-made denture can loosen as the foundation shifts. What happens during a same-day reline? After a fit assessment, we take a precision impression or scan inside your denture, process the new fitting surface in our on-site lab, then refit, adjust, and polish so you can leave with improved comfort the same day in many cases. How long will results last, and how often should fit be reassessed? Relines typically last 1 to 3 years, and we recommend an annual check. Rebases extend the life of your current teeth with a refreshed base, but timing varies. Full replacement is often evaluated around 5 to 10 years. The takeaway A loose denture does not mean starting over. A targeted reline can restore close contact and comfort when the denture is otherwise sound. When the base itself needs renewal, a rebase strengthens the foundation while preserving the teeth you already like.

If your dentures feel loose or you worry about them shifting when you talk or eat, you are not alone. Many people find that even well-made conventional dentures can move as the jawbone changes over time. That movement can chip away at daily confidence. Implant-supported removable dentures offer a reassuring alternative. By anchoring your denture to a few strategically placed dental implants, you gain stability, improved chewing, and a more secure feel in day-to-day life. At Sullivan Denture Centre in Surrey, our denturists combine clinical expertise with an on-site laboratory to plan, build, and refine implant-retained solutions with precision and care. This guide explains how implant-supported dentures work, who might benefit, what the typical timeline looks like, and how we coordinate with your dentist or surgeon from start to finish. What implant-supported removable dentures are An implant-supported removable denture is a custom denture that attaches to dental implants, which act as artificial tooth roots. The implants are placed in the jawbone by a dentist or oral surgeon. After healing, small connectors called locators or a slim bar framework are secured to the implants. Your denture then clicks into place on those attachments. You can remove the denture for daily cleaning, yet it stays more stable during eating and speaking. Because implants stimulate the jawbone in a way similar to natural roots, this approach can help slow bone resorption. That often translates to a more consistent fit over time and improved comfort compared with a conventional denture that relies solely on suction and soft tissue support. Who is a good candidate Most candidates share a few key traits, which we confirm during a comprehensive consultation: Adequate bone volume and density in the jaw to support implants, or a treatment plan from your surgeon to build bone where needed. Healthy gums and oral tissues. Any inflammation or infection should be treated first. A medical history that allows for minor oral surgery and implant healing. We routinely review medications and conditions and coordinate with your dental and medical providers as needed. If you have experienced significant denture looseness, sore spots from rubbing, difficulty chewing certain foods, or diminished confidence because of movement, implant retention may be worth discussing. Our team also supports complex cases with advanced digital planning and in-house lab capabilities, which can improve precision in challenging anatomies. How stability, speech, and chewing improve Conventional dentures sit on the gums. Even with a good fit, normal jaw movements and gradual bone changes can lead to rocking and loss of suction. Implant-supported dentures gain retention from the implants, so the denture resists lifting and side-to-side movement. This typically provides: Stability you can feel. The denture engages the locator attachments or bar, so it clicks into a repeatable position and resists displacement during function. Clearer speech. Reduced movement helps maintain consistent tongue and lip positioning, which can support clearer pronunciation of sounds that often challenge denture wearers. More efficient chewing. With less sliding and tipping, you can usually bite and chew a wider range of foods more comfortably, which supports nutrition and confidence. While results vary, many patients report less need for adhesive and fewer sore spots because the denture is not relying entirely on soft tissue for retention. Our collaborative workflow and timeline We take a team-based approach built around your goals, your health, and precise fabrication in our on-site lab. Consultation with a denturist. We review your history, examine your oral tissues, discuss expectations, and take impressions or digital scans as appropriate. If you have a referring dentist or surgeon, we connect directly to coordinate planning. If you are starting fresh, we can help you organize the surgical referral. Digital planning and try-ins. Where beneficial, we use digital scanning and 3D workflows to design your denture and verify esthetics and function before finalizing. A wax or printed try-in allows you to see tooth shape and position, and gives us the chance to refine bite, lip support, and phonetics. Implant placement and healing. Your dentist or surgeon places the implants. Healing periods vary based on bone quality and the specific system used. During this time, you may wear a modified temporary denture. We provide guidance on comfort and hygiene, and we remain in contact with your surgical team. Attachment selection. Once your surgeon confirms integration, we attach locator abutments or a bar system to the implants. Choice depends on your anatomy, number and position of implants, and your maintenance preferences. Final connection and refinement. Your denture is fitted to the attachments and adjusted chairside. Because we fabricate and refine in our in-house lab, we can make timely adjustments to optimize comfort and retention. Follow-ups are scheduled to monitor tissues and make any fine-tuning changes. Healing timelines can vary. Your denturist will explain what to expect at each stage, including comfort tips and hygiene routines so you feel prepared throughout the process. The strength of an in-house lab Having an on-site laboratory means tighter control over quality and timing. If a small adjustment is needed during a try-in, we can often handle it the same day. If a clip, housing, or fit surface needs refinement after attachment, we can address it quickly without shipping delays. This continuity supports a smoother experience and helps maintain precision from planning to delivery. Coordinating with your dentist or surgeon Successful implant-supported dentures rely on teamwork. We: Share records and treatment goals early so implant positions support your planned tooth setup and bite. Confirm timelines together, including when to uncover implants and place attachments. Provide your dentist or surgeon with the design details of the locator or bar system, ensuring component compatibility and a predictable fit. Keep you informed at every step so there are no surprises. Whether you come to us through a referral or seek us out directly, we respect your existing care relationships and integrate seamlessly to keep your journey organized and clear. Caring for implant-supported dentures Daily care remains important. Clean your denture and attachments every day with non-abrasive cleansers. Brush gently around the locator abutments or bar to remove plaque. Schedule regular maintenance visits with your denturist. Just like tires on a car, retention components can wear and are replaceable. Expect periodic checks, occasional part replacements, and relines over the years as tissues evolve. These steps help preserve comfort and protect your investment. For general guidance on keeping removable prosthetics functioning well, you may find our perspective on relines and rebasing useful. When relining cannot restore fit, we discuss options together in a supportive, stepwise way.
