Oral habits like thumb sucking, finger sucking, and tongue thrusting feel comforting to children, but when they continue past age 4-5, these habits can significantly affect dental development, facial growth, and speech. At Dental Sedation Ottawa, we provide custom habit appliances (also called habit breakers or habit-breaking devices) to help your child overcome these patterns gently and effectively. And with our comprehensive sedation options, even anxious children can have these appliances fitted comfortably and stress-free.
Habit appliances are custom-made orthodontic devices designed to discourage persistent oral habits that can harm your child's dental and facial development. These small appliances work by serving as gentle reminders or creating a physical barrier that makes the habit uncomfortable or impossible to continue, helping your child break the pattern naturally.
Think of them as training wheels for breaking oral habits—they provide structure and support while your child's brain learns new patterns. Most children adapt quickly and overcome their habits within 3-6 months of wearing the appliance.
The most common habit appliances address three primary concerns: thumb sucking or finger sucking, tongue thrusting (pushing the tongue forward against or between teeth during swallowing), and tongue positioning problems (resting the tongue between or against front teeth).
These habits might seem harmless, but when they persist beyond early childhood (typically past age 4-5), they can cause serious orthodontic problems: protruding front teeth ("buck teeth"), open bites (upper and lower front teeth don't touch when biting), crossbites, narrow upper jaws, speech problems (especially with "s," "z," and "th" sounds), and changes in facial growth patterns.
The good news? Habit appliances have excellent success rates—typically 85-95%—when used properly and with parental support. They work best when your child is motivated to stop the habit and understands why the appliance is necessary.
At Dental Sedation Ottawa, we understand that getting a new appliance can feel overwhelming for some children, especially those with anxiety about dental visits. While habit appliance placement is usually straightforward and quick, we offer sedation options for children who need extra comfort support.
Different habits require different appliance designs. Your dentist recommends the most appropriate type based on which habit needs correction, your child's age, dental development, and motivation level.
Not every child with oral habits needs a habit appliance. Most dental experts recommend monitoring oral habits until around age 4-5, as many children naturally outgrow thumb sucking and tongue issues on their own during this developmental period.
Signs Your Child May Need a Habit Appliance: Persistent habits after age 4-5 (especially if frequent or intense), dental changes already developing (protruding teeth, open bite, crossbite), failed non-appliance interventions (positive reinforcement, bandages, bitter-tasting products), speech problems from tongue thrusting, social concerns or self-consciousness at school, orthodontic planning needs, or vigorous thumb sucking for hours daily.
When to Wait: Children under age 4-5 who might naturally outgrow the habit, habits that occur rarely or briefly, children going through major life stressors where the habit provides emotional support, medical or developmental concerns, or children not developmentally ready to cooperate.
Your dentist assesses the severity of the habit, examines any existing dental changes, considers your child's age and emotional readiness, and discusses whether a habit appliance is appropriate or if continued monitoring makes more sense.
Before the appliance placement appointment, we take detailed impressions (molds) of your child's upper teeth. These impressions go to a dental laboratory where technicians fabricate the custom appliance—usually ready within 2-3 weeks. We also take photographs and X-rays to document your child's current dental condition.
At the fitting appointment, we begin by administering your chosen sedation option if needed. For most children, nitrous oxide provides adequate relaxation, though some require deeper sedation. Once comfortable, we ensure your child can tolerate the sensations in their mouth. The dentist first fits stainless steel bands around the upper first molars (the large back teeth). These bands are similar to orthodontic bands—they fit snugly around the teeth like rings. We try on the bands, make any necessary adjustments for perfect fit, then cement them securely in place. Next, the habit appliance—which has extensions that attach to the bands—is carefully positioned. For fixed appliances like cribs and rakes, the wire or plastic extensions are soldered or welded to the bands. The entire appliance is then cleaned, polished, and checked to ensure it's comfortable, doesn't interfere with eating or speaking, and effectively interrupts the target habit.
Taking initial impressions takes 10-15 minutes. The appliance placement appointment typically requires 45-60 minutes for careful fitting, cementation, and instruction.
The first 2-3 days with a new habit appliance involve adaptation. Your child will feel the appliance constantly and may find it strange or uncomfortable initially. Speech might sound slightly different (especially "s" and "th" sounds), but this resolves within 3-5 days as the tongue adapts. Eating requires some adjustment—start with soft foods and gradually return to normal diet. Some irritation of the tongue or lips may occur during the first week as soft tissues adapt to the appliance. Dental wax (which we provide) can cover any rough areas temporarily. These irritations resolve quickly as the mouth adjusts.
Brush carefully around the appliance twice daily, paying special attention to cleaning where the bands meet the teeth and around the wires or prongs. Food particles can trap around habit appliances more easily than around natural teeth alone. Use a proxy brush (tiny Christmas tree-shaped brush) or floss threader to clean under wires. Avoid very sticky foods (caramel, taffy, gummy candies) that could pull the appliance loose. Don't bite into hard foods like apples or carrots with front teeth—cut them into small pieces. Ice, hard candies, and chewing on non-food objects should be avoided.
Most children attempt their habit once or twice after appliance placement, find it uncomfortable or unsatisfying, and quickly stop trying. The habit typically breaks within 2-4 weeks. However, the appliance remains in place for 6-12 months to ensure the habit pattern is completely eliminated and doesn't return. For tongue thrusting, the appliance retrains the tongue to proper resting position and correct swallowing patterns over 3-6 months. This retraining is gradual—your child won't notice day-to-day changes, but over weeks and months, new patterns become automatic.
We schedule follow-up appointments every 4-8 weeks to monitor appliance condition, check oral hygiene, assess habit cessation progress, and evaluate any dental changes. Once the habit is reliably broken and sufficient time has passed to ensure it won't return, we schedule appliance removal—a quick, easy 15-minute appointment that requires no anesthesia or sedation. Call us at (613) 482-0501 if the appliance becomes loose or breaks, persistent pain or sores develop, bands are cutting into gums, difficulty eating or speaking doesn't improve after the first week, or the child finds ways to continue the habit despite the appliance.
Habit appliances typically cost starting at $600-900, including impressions, laboratory fabrication, placement appointment, and follow-up care. Appliance removal is usually included in this fee. If sedation is needed for placement, sedation fees are additional.
When you consider that oral habits left uncorrected often lead to significant orthodontic problems requiring $4,000-8,000 in braces treatment, open bite correction ($5,000-10,000), or even jaw surgery in severe cases ($15,000-30,000), habit appliances represent exceptional preventive value. The relatively small upfront investment can prevent thousands in future treatment costs.
Many dental insurance plans cover habit appliances at 50-80% when deemed medically necessary to prevent or correct dental problems. We provide direct billing to major insurance carriers and accept the Canadian Dental Care Plan (CDCP). Our team reviews your insurance coverage and direct billing options during consultation and provides comprehensive cost estimates before treatment begins.
